Gold Mining & Refining: "South Dakota Saga" 1941 Homestake Mining Company

"Gold mining and the life of gold miners in South Dakota, as seen by the mining company." Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Gold_mining Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Gold mining is the removal of gold from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Panning Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan. The panning material is usually removed from stream beds, often at the inside turn in the stream, or from the bedrock shelf of the stream, where the density of gold allows it to concentrate, a type called placer deposits. Gold panning is the easiest technique for searching for gold, but is not commercially viable for extracting gold from large deposits, except where labor costs are very low or gold traces are substantial. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to identify placer gold deposits to be evaluated for commercial viability. Sluicing Using a sluice box to extract gold from placer deposits has long been a common practice in prospecting and small scale mining. A sluice box is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold bearing material is placed at the top of the box. The material is carried by the current through the box where gold and other dense material settles out behind the riffles. Less dense material flows out of the box as tailings. Larger commercial placer mining operations employ screening plants, or trommels, to remove the larger alluvial materials such as boulders and gravel, before concentrating the remainder in a sluice box or jig plant. These operations typically include diesel powered, earth moving equipment, including excavators, bulldozers, wheel loaders, and rock trucks. Dredging Although this method has largely been replaced by modern methods, some dredging is done by small scale miners using suction dredges... Gold ore processing In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used. Cyanide process Cyanide extraction of gold may be used in areas where fine gold bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zinc is to precipitate out residual zinc as well as the silver and gold metals. The zinc is removed with sulfuric acid, leaving a silver or gold sludge that is generally smelted into an ingot then shipped to a metals refinery for final processing into 99.9999% pure metals. Advancements in the 1970s have seen activated carbon used in extracting gold from the leach solution. The gold is absorbed into the porous matrix of the carbon. Activated carbon has so much internal surface area,[5] that fifteen grams (half an ounce) has the equivalent surface area of the Melbourne Cricket Ground (18,100 square metres (195,000 sq ft)). The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning... The cyanide technique is crude and is commonly used in low grade gold and silver ore processing. There are many environmental hazards associated with this extraction method in addition to the high toxicity of the cyanide itself. An acute example was demonstrated in the 2000 Baia Mare cyanide spill environmental disaster when a break in a waste pond dam gold mine reprocessing facility near Baia Mare in northern Romania released approximately 100,000 cubic metres (3,500,000 cu ft) of waste water contaminated with heavy metal sludge and up to 120 long tons (122 t) of cyanide into the Tisza River...

Mapping resources that matter: Paul Bauman at TEDxCanmore
 
17:08
Talk Overview 90% of geophysicists in the world explore for oil and gas. Another 5% explore for mineral resources. And another 4.9% teach and regulate the previous 95%. In today's world, fluctuating commodity prices and mountainous stockpiles of recycled metals tell us that we have too much oil, uranium, coal, and iron ore. Today and in the foreseeable future, what the world is drastically scarce of is clean water, clean soil, and a common cultural legacy. Those remaining less than 0.1% of geophysicists not accounted for, above, are dedicated to developing techniques to explore for potable water, mapping soil salinization, demining previously productive agricultural land, and delineating subsurface remains of culturally rich sites threatened by development. With examples from Africa, Asia, Australia, and the Middle East, we can see how these non-destructive subsurface investigation techniques can radically improve life not only on a local and regional scale, but even on a continent wide scale. And where we are not using these approaches, we can envision how the development of access to clean water, clean soil, and mankind's cultural legacies can be greatly improved. Speaker Profile Paul Bauman is the Technical Director of the Geophysics group at WorleyParsons, in Calgary, where he has been working since 1990. He is one of the world experts on near surface applications of borehole and surface geophysical methods as applied to investigations in water resources, archaeology, soil science, geotechnical engineering, subsurface contamination, and geohazard identification. Paul has a B.Sc.E. in Geological Engineering from Princeton University, a Minor in Near Eastern Studies from Princeton, and an M.Sc. in Earth Sciences from the University of Waterloo. Paul has published widely in peer reviewed journals, scientific volumes, and conference proceedings. He has presented geophysical papers at over 100 conferences in an extraordinarily wide range of disciplines including geophysics, soil science, hydrogeology, disaster relief, archaeology, water resource development, contaminant hydrogeology, mining, mine waste management, heavy oil, shallow gas, salt water intrusion, salt water intrusion, etc. He has been an invited speaker at many educational, professional, and government institutions including Princeton University, Boston University, California State, the University of Pennsylvania, the National Water Authority in Yemen, the Israel Museum in Jerusalem, the Royal BC Museum, and the Prince of Wales Northern Heritage Centre in Yellowknife. Aspects of his archaeogeophysical work have been the subject of a NOVA documentary (Ancient Refuge in the Holy Land), numerous radio and television interviews, a National Geographic movie entitled "Finding Atlantis," and numerous newspaper and magazine articles including in Time, National Geographic, and the Reader's Digest. Paul's work in the Cave of Letters and other sites is featured in the recently published popular books Secrets of the Cave of Letters: Rediscovering a Dead Sea Mystery; Digging Through the Bible: Modern Archaeology and the Ancient Bible; and Digging through History: Archaeology and Religion from Atlantis to the Holocaust. Ongoing archaeogeophysical projects include the subsurface imaging of a Roman bath house from the time of Jesus, located in Nazareth; the geophysical mapping of the ancient Phoenician harbour of Tel Akko, perhaps the first constructed harbour in the world; and the geophysical mapping of the destroyed and buried remains of a World War II Nazi extermination camp at Sobibor, Poland. A few water resource projects of note include the introduction of an entirely new approach to water exploration in Africa, which raised success rates in drilling from less than 20% to over 90% in Malawi; innovative and successful geophysical water exploration programs in Yemen which tapped previously unused aquifers in areas that had gone years without significant rainfall; and the secondment to UNICEF to assess the impact of the 2004 Boxing Day Tsunami to the water resources of Aceh Province in Indonesia, and to begin the redevelopment and rehabilitation of water supplies to the region -- besides being an experienced geophysicist and hydrogeologist, Paul speaks fluent Indonesian and Malay.

Resistivity Testing explained, Locating Gold underground
 
03:56
In this video, we used a "Resistivity Meter" to detect gold bearing veins below the surface in order to pinpoint the exact location, depth, and width of such veins. By using this Geophysics technology, we were able to save time, energy and money to locate Gold deposits. This also preserves the environment and eliminates the need to aimlessly dig around looking for some "pot of gold"! By uploading this video, I'm hoping others can utilize this information to get a better understanding of the some of the processes involved in Gold mining. This step/process occurs after you've been properly advised by a geologist that a certain area has the potential to have gold bearing veins below the surface. Simply put, its a technical means of figuring out where and what type of gold deposit could be laying underground. These kind of things...I never learned in school. Though, I wish I had because I would have been doing this a long time ago. Through my own research and from the help of others; Gold mining (and the technical techniques involved) has become one of my great passions. The exploitation of this one element - Gold, has the potential to completely change the landscape of a country's economic landscape. But that's another story. :) There are other Geophysical techniques too that can be utilized to locate Gold deposits below the surface. Yet the resistivity method is a less cost intensive technique. We hired Mr. Eugene from South Africa to conduct the test and learned a great deal. At the end, we received a very professional report that gave us very detailed information regarding whether or not there were possible gold veins. It also gave us insight on whether it was worth investing more money to investigate the deposit even further.

How Do You Find a Gold Vein? Mining 101: Ep 12.
 
02:33
Chairman of Exeter Resource Corp. Yale Simpson explains how you find a vein that is worth mining. From wiki: The difference between 19th century and modern mining techniques and the type of ore sought is based on the grade of material being mined and the methods of mining which are used. Historically, hand-mining of gold ores permitted the miners to pick out the lode quartz or reef quartz, allowing the highest-grade portions of the lodes to be worked, without dilution from the unmineralised wall rocks. Modern mining using larger machinery and equipment forces the miners to take low-grade waste rock in with the ore material, resulting in dilution of the grade. However, modern mining and assaying allows the delineation of lower-grade bulk tonnage mineralisation, within which the gold is invisible to the naked eye. In these cases, veining is the subordinate host to mineralisation and may only be an indicator of the presence of metasomatism of the wall-rocks which contains the low-grade mineralisation. For this reason, veins within hydrothermal gold deposits are no longer the exclusive target of mining, and in some cases gold mineralization is restricted entirely to the altered wall rocks within which entirely barren quartz veins are hosted.

In the end you will come out with a fundamental understanding of where to use what piece of equipment and why.

Gold Mining: "South Dakota Saga" (1941) Homestake Mining Company 33min
 
32:39
"Gold mining and the life of gold miners in South Dakota, as seen by the mining company." https://en.wikipedia.org/wiki/Gold_mining Gold mining is the removal of gold from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Panning Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan. The panning material is usually removed from stream beds, often at the inside turn in the stream, or from the bedrock shelf of the stream, where the density of gold allows it to concentrate, a type called placer deposits. Gold panning is the easiest technique for searching for gold, but is not commercially viable for extracting gold from large deposits, except where labor costs are very low or gold traces are substantial. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to identify placer gold deposits to be evaluated for commercial viability. Sluicing Using a sluice box to extract gold from placer deposits has long been a common practice in prospecting and small scale mining. A sluice box is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold bearing material is placed at the top of the box. The material is carried by the current through the box where gold and other dense material settles out behind the riffles. Less dense material flows out of the box as tailings. Larger commercial placer mining operations employ screening plants, or trommels, to remove the larger alluvial materials such as boulders and gravel, before concentrating the remainder in a sluice box or jig plant. These operations typically include diesel powered, earth moving equipment, including excavators, bulldozers, wheel loaders, and rock trucks. Dredging Although this method has largely been replaced by modern methods, some dredging is done by small scale miners using suction dredges... Gold ore processing In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used. Cyanide process Cyanide extraction of gold may be used in areas where fine gold bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zinc is to precipitate out residual zinc as well as the silver and gold metals. The zinc is removed with sulfuric acid, leaving a silver or gold sludge that is generally smelted into an ingot then shipped to a metals refinery for final processing into 99.9999% pure metals. Advancements in the 1970s have seen activated carbon used in extracting gold from the leach solution. The gold is absorbed into the porous matrix of the carbon. Activated carbon has so much internal surface area,[5] that fifteen grams (half an ounce) has the equivalent surface area of the Melbourne Cricket Ground (18,100 square metres (195,000 sq ft)). The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required. The cyanide technique is crude and is commonly used in low grade gold and silver ore processing. There are many environmental hazards associated with this extraction method in addition to the high toxicity of the cyanide itself. An acute example was demonstrated in the 2000 Baia Mare cyanide spill environmental disaster when a break in a waste pond dam gold mine reprocessing facility near Baia Mare in northern Romania released approximately 100,000 cubic metres (3,500,000 cu ft) of waste water contaminated with heavy metal sludge and up to 120 long tons (122 t) of cyanide into the Tisza River...

Primitive Technology: Forge Blower
 
04:32
I invented the Bow Blower, a combination of the bow drill and forge blower to make a device that can force air into a fire while being easy to construct from commonly occurring natural materials using only primitive technology. I began by fanning a fire with a piece of bark to increase its temperature. It is this basic principle I improved on throughout the project. Next, I made a rotary fan from two pieces of bark that slot together at right angles to each other to form a simple 4 bladed paddle wheel about 20 cm in diameter and 5 cm tall. The blades of the fan were not angled and were designed only to throw air outwards away from the axle when spun. The rotor of the fan was made by splitting a stick two ways so it formed 4 prongs. The fan was then inserted into the prongs and the end lashed to hold it in place. Spinning the fan rotor back and forth between the palms of the hands fanned the fire. But only some of the wind generated by the fan reached the fire. The rest of it was blowing in other directions, effectively being wasted. So I built a fan housing from unfired clay to direct the air flow into the fire. This was basically an upturned pot with a hole in the top, a spout coming out of the side. The housing was about 25 cm wide and 8 cm tall. The hole in the top and the spout were both about 6 cm in diameter so that the air coming in roughly equalled the air coming out. The base of the fan rotor sat in a wooden socket placed in the ground to make it spin easier and the top of the rotor protruded from the hole in the top of the housing. Now when the fan spun, air entered the hole in the top of the housing and exited the spout in the side. Importantly, it doesn’t matter which way the fan spins, air always goes into the inlet and out the spout. Air is thrown out towards the walls of the housing and can only leave through the spout while the vacuum in the centre sucks new air into the housing through the inlet. A separate clay pipe called a tuyere was made to fit over the spout to direct air into the coals. This was done because the pipe that touches the fire can melt away so it’s better to make this part replaceable. Instead of making a large wheel and belt assembly to step up the speed of rotation, I opted for a 75 cm long bow. I made a frame to hold the rotor in place consisting of two stakes hammered into the ground with a socketed cross bar lashed on to hold the top of the rotor. I made bark fibre cordage and tied the end to a stick. I then looped the cord around the rotor and held the other end in the same hand holding the stick. I then pushed and pulled the bow causing the rotor to spin rapidly, forcing air into the fire. I made a simple mud furnace for the blower. Then I collected orange iron bacteria from the creek (iron oxide), mixed it with charcoal powder (carbon to reduce oxide to metal) and wood ash (flux to lower the melting point) and formed it into a cylindrical brick. I filled the furnace with charcoal, put the ore brick in and commenced firing. The ore brick melted and produced slag with tiny, 1mm sized specs of iron through it. My intent was not so much to make iron but to show that the furnace can reach a fairly high temperature using this blower. A taller furnace called a bloomery was generally used in ancient times to produce usable quantities of iron and consumed more charcoal, ore and labour. This device produces a blast of air with each stroke of the bow regardless of whether it is pushed or pulled. The bow makes it possible to operate the blower without using a complicated belt and wheel assembly used in traditional forge blowers. There is a brief pause at the end of each stroke where the fan stops to rotate in the other direction, but this is effectively no different to the intermittent blast of a double acting bellows of Europe or box bellows of Asia. The materials used (wood, bark, bark fibre and clay) are readily available on most continents. No leather, valves or precisely fitted piston gaskets are required as with other types of bellows. The cords for this device wear out often so a number of back up cords should be kept handy for quick replacement. In summary, this is an easy to make device that solves the problem of supplying forced combustion air required for high temperature furnaces and forges.

These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. De Re Metallica, Georgius Agricola, 1550, Book I, Para. 1Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.

These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. De Re Metallica, Georgius Agricola, 1550, Book I, Para. 1Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.

GOLD - WikiVidi Documentary
 
01:05:52
Gold is a chemical element with symbol Au and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium . Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars, and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core. Therefore, most of the gold that is in the Eart... http://www.wikividi.com ____________________________________ Shortcuts to chapters: 00:03:50: Characteristics 00:05:15: Color 00:06:53: Isotopes 00:08:36: Synthesis 00:10:58: Chemistry 00:15:03: Rare oxidation states 00:17:08: Occurrence 00:22:22: Seawater 00:24:09: History 00:31:41: Etymology 00:32:23: Culture 00:34:36: Mining and prospecting 00:38:24: Extraction and refining 00:39:56: Consumption 00:40:40: Pollution 00:42:56: Monetary use 00:49:01: Price 00:50:03: History 00:54:29: Jewelry 00:56:31: Electronics 00:59:30: Medicine ____________________________________ Copyright WikiVidi.

Finding Gold with metal detectors - where to look, what to do. Find gold by viewing the other films in this series for all the methods (from simple hand tools to metal detectors) plus even more valuable gems. Gold and platinum are 15-19 times heavier than other streambed materials and concentrate in low pressure areas and cracks that run across rivers and streams. You look for a crack on the bank, and follow it out until you meet the "gold line" and there you suck it out with your dredge. Gold will be on the outside edge of a river gravel bar, at the head of the bar (large gold but usually beneath big boulders), and at the tail end of a bar (vast concentrations due to river bars forming in the shape of an airfoil and sucking fine gold to the tail end) but be small to microscopic at the tail end. Gold will travel down a river or stream in a line, usually off center of the high pressure water. Gold will settle behind a boulder. A good place to fish, can also be an excellent place to find gold. "Black sand" is iron ore that can be readilly identified in gravel bars and is a ready indicator that gold is probably present. The most effective and economical way for the average person to find paying concentrations of gold in a river or stream is with a simple ($80) sluice that you shovel into and the riffles retain gold, platinum, gems and anything heavy for you. Gold can be found up high on the old river channels and recovered with metal detectors, a gold wheel, a highbanker, or simply by identifying the material, shoveling it in your truck and working it out later in a wheel, or your simple stream sluice. The states which have gold in vast quantities are: Maine, Vermont, Virginia, North Carolina, South Carolina, Georgia, Alabama, Colorado, Wyoming, New Mexico, Nevada, Arizona, California, Idaho, Washington, Montana, and Oregon. The rest have gold as well, some in very good concentrations. All have gems of some kind that a sluice will seperate and hold. Good luck finding the gold of your dreams!

Chniese in Zambia - Straight through Africa
 
43:55
Forty years ago, the Chinese laid a train track through Zambia. Bram Vermeulen travels through the African country by train to discover how the relationship between these countries is now. Zambia and China are old friends. When the African country became independent in 1964, the Asians were the first to queue to lend a helping hand. Communist China, itself still poor, took the lead in the construction of a railway that ran through Zambia and neighboring Tanzania to the port city of Dar es Salaam. Of course, that was not only out of kindness; the Chinese saw trade opportunities in the area. More than forty years later, it turns out that the railroad ran into a grandiose failure that cost China a lot of money - you can read more about this in this story by Sean van der Steen, with beautiful photographs. However, the Chinese presence in Zambia has become indispensable, Bram notes. He comes across them along the train route. For example, Chinese people run a copper mine, breed chickens on a large scale and have large factories. Zambians work on this economic activity, under Chinese bosses. Not everybody is happy with that. Bram visits a village where an explosives factory has exploded. The Chinese owners had not taken it so closely with the safety regulations. The incident is illustrative of the working methods of Chinese in Africa: care for the employees is subordinate to the profits. Also in a copper mine, it appears that the working conditions are far from ideal, and that employees openly complain about their low salary. De opzichter van de mijn beklaagt zich op zijn beurt over de arbeiders: hij vindt Zambianen maar onhandig en lui. ‘We trainen al vele jaren Zambiaanse arbeiders. Er is een groot verloop onder het personeel. Ze gaan naar andere bedrijven zodra ze vaardigheden hebben verworven.’ Het zijn trouwens niet alleen Zambianen die met de arbeidsomstandigheden in hun maag zitten. Chinees personeel, dat letterlijk niet mag klagen, doet tegen Bram toch een boekje open. Het leven op een afgesloten compound, ver van familie en vrienden, bestaat bijna geheel uit werk en verplichte culturele activiteiten. Van integratie is geen sprake. Maar het is niet allemaal kommer en kwel. Ondernemende Zambianen vertrekken naar China en komen soms steenrijk terug. Een man die met een Chinese partner een textielbedrijf begon, leidt Bram rond door zijn grote huis. Zambianen kunnen in eigen land niet op tegen de Chinese concurrentie, zegt hij, en daar zou de overheid iets aan moeten veranderen. Het zou volgens hem veel helpen als buitenlandse ondernemers net als in China verplicht zouden worden een Zambiaanse partner in de arm te nemen. De vicepresident van het land erkent dat er problemen zijn. Chinese boeren verdringen de Zambianen, er wordt gesjoemeld met werkvergunningen, alle winst verdwijnt naar China. Werken is alles wat de Chinezen doen, zeven dagen per week, en ze eisen hetzelfde van hun Zambiaanse personeel. De oude communistische vriend heeft feitelijk kapitalisme in zijn puurste vorm in het land geïntroduceerd. Episode 5. A trail of Chinese Forty years ago, the Chinese built a railway through Zambia.

Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy, and the sudden population increase allowed California to go rapidly to statehood, in the Compromise of 1850. The Gold Rush had severe effects on Native Californians and resulted in a precipitous population decline from disease, genocide and starvation. By the time it ended, California had gone from a thinly populated ex-Mexican territory, to having one of its first two U.S. Senators, John C. Frémont, selected to be the first presidential nominee for the new Republican Party, in 1856. The effects of the Gold Rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, called "forty-niners" (referring to 1849, the peak year for Gold Rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii), and Latin America in late 1848. Of the approximately 300,000 people who came to California during the Gold Rush, about half arrived by sea and half came overland on the California Trail and the Gila River trail; forty-niners often faced substantial hardships on the trip. While most of the newly arrived were Americans, the gold rush attracted thousands from Latin America, Europe, Australia, and China. Agriculture and ranching expanded throughout the state to meet the needs of the settlers. San Francisco grew from a small settlement of about 200 residents in 1846 to a boomtown of about 36,000 by 1852. Roads, churches, schools and other towns were built throughout California. In 1849 a state constitution was written. The new constitution was adopted by referendum vote, and the future state's interim first governor and legislature were chosen. In September 1850, California became a state. At the beginning of the Gold Rush, there was no law regarding property rights in the goldfields and a system of "staking claims" was developed. Prospectors retrieved the gold from streams and riverbeds using simple techniques, such as panning. Although the mining caused environmental harm, more sophisticated methods of gold recovery were developed and later adopted around the world. New methods of transportation developed as steamships came into regular service. By 1869, railroads were built from California to the eastern United States. At its peak, technological advances reached a point where significant financing was required, increasing the proportion of gold companies to individual miners. Gold worth tens of billions of today's US dollars was recovered, which led to great wealth for a few, though many who participated in the California Gold Rush earned little more than they had started with.

Primitive Technology: Wattle and Daub Hut
 
11:14
I built this hut in the bush using naturally occurring materials and primitive tools. The hut is 2m wide and 2m long, the side walls are 1m high and the ridge line (highest point) is 2m high giving a roof angle of 45 degrees. A bed was built inside and it takes up a little less than half the hut. The tools used were a stone hand axe to chop wood, fire sticks to make fire, a digging stick for digging and clay pots to carry water. The materials used in the hut were wood for the frame, vine and lawyer cane for lashings and mud for walls. Broad leaves were initially used as thatch which worked well for about four months before starting to rot. The roof was then covered with sheets of paper bark which proved to be a better roofing material (*peeling the outer layer of bark does not kill this species of tree). An external fireplace and chimney were also built to reduce smoke inside. The hut is a small yet comfortable shelter and provides room to store tools and materials out of the weather. The whole hut took 9 months from start to finish. But it only took 30 days of actual work (I abandoned it for a few months before adding bark roof, chimney and extra daub ).

The California Gold Rush Experience: Facts, Miners, Timeline, Towns (1998)
 
01:24:51
The California Gold Rush (1848–1855) began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. About the book: https://www.amazon.com/gp/product/0671255371/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0671255371&linkCode=as2&tag=tra0c7-20&linkId=e466e8af410d510aab178d97d3765afc The first to hear confirmed information about gold in California were residents of Oregon, the Sandwich Islands (Hawaii), western Mexico, and Central America. They were the first to go there in late 1848. All told, the news of gold brought some 300,000 people to California from the rest of the United States and abroad. Of the 300,000, approximately half arrived by sea and half came overland from the east, on the California Trail and the Gila River trail. The gold-seekers, called "forty-niners" (as a reference to 1849), often faced substantial hardships on the trip. While most of the newly arrived were Americans, the Gold Rush attracted tens of thousands from Latin America, Europe, Australia, and Asia. At first, the gold nuggets could be picked up off the ground. Later, gold was recovered from streams and riverbeds using simple techniques, such as panning. More sophisticated methods were developed and later adopted elsewhere. At its peak, technological advances reached a point where significant financing was required, increasing the proportion of gold companies to individual miners. Gold worth tens of billions of today's dollars was recovered, which led to great wealth for a few. However, many returned home with little more than what they had started with. The effects of the Gold Rush were substantial. San Francisco grew from a small settlement of about 200 residents in 1846 to a boomtown of about 36,000 by 1852. Roads and other towns were built throughout California. In 1849 a state constitution was written, and a governor and legislature were chosen. California became a state as part of the Compromise of 1850. New methods of transportation developed as steamships came into regular service. By 1869 railroads were built across the country from California to the eastern United States. Agriculture and ranching expanded throughout the state to meet the needs of the settlers. At the beginning of the Gold Rush, there was no law regarding property rights in the goldfields and a system of "staking claims" was developed. The Gold Rush also resulted in attacks on Native Americans, who were forcibly removed from their lands. An estimated 100,000 California Indians died between 1848 and 1868, and some 4,500 of them were murdered. Gold mining also caused environmental harm to rivers and lakes. Overnight California gained the international reputation as the "golden state".[138] Generations of immigrants have been attracted by the California Dream. California farmers,[139] oil drillers,[140] movie makers,[141] airplane builders,[142] and "dot-com" entrepreneurs have each had their boom times in the decades after the Gold Rush.[143] The literary history of the Gold Rush is reflected in the works of Mark Twain (The Celebrated Jumping Frog of Calaveras County), Bret Harte (A Millionaire of Rough-and-Ready), Joaquin Miller (Life Amongst the Modocs), and many others.[29][144] Included among the modern legacies of the California Gold Rush are the California state motto, "Eureka" ("I have found it"), Gold Rush images on the California State Seal,[145] and the state nickname, "The Golden State", as well as place names, such as Placer County, Rough and Ready, Placerville (formerly named "Dry Diggings" and then "Hangtown" during rush time), Whiskeytown, Drytown, Angels Camp, Happy Camp, and Sawyers Bar. The San Francisco 49ers National Football League team, and the similarly named athletic teams of California State University, Long Beach, are named for the prospectors of the California Gold Rush. In addition. the standard route shield of state highways in California is in the shape of a miner's spade to honor the California Gold Rush.[146][147] Today, aptly named State Route 49 travels through the Sierra Nevada foothills, connecting many Gold Rush-era towns such as Placerville, Auburn, Grass Valley, Nevada City, Coloma, Jackson, and Sonora.[148] This state highway also passes very near Columbia State Historic Park, a protected area encompassing the historic business district of the town of Columbia; the park has preserved many Gold Rush-era buildings, which are presently occupied by tourist-oriented businesses. http://en.wikipedia.org/wiki/California_gold_rush
