Mining reaps huge profits for the companies that own them and provides employment to a large number of people. It is also a huge source of revenue for the government. Despite its economic importance, the effects of mining on the environment is a pressing issue. Mining activities require the clearing of large areas of land. The chemicals used in the mining process often escape into the environment causing pollution. Watch this video to know how mining affects the environment.

Very intriguing discover as I was checking out an old mine site. Obviously someone had been working this site in the last few days. The left fresh Pyrrhotite rocks on the surface. Pyrrhotite, an Iron sulphide, oxidises easily. It rained heavily the day before, which probably help out with the oxidation process. When I arrived, I found a rock of Pyrrhotite lay on on the surface smoking. My theory is that it is oxidizing so fast and creating so much heat, that it is basically burning on its own. A bit like natural ore roasting.

Applications Extraction of iron from its oxides:In a Blast furnace Oxide ores of iron, after concentration through calcination/roasting are mixed with limestone and coke are fed from its top.Hot air is blown from the bottom of the furnace and coke is burnt to give temperature upto about 2200K in the lower portion itself. The burning of coke therefore supplies most of the heat required in the process and will be oxidised to CO. The CO and heat moves to upper part of the furnace. In upper part, the temperature is lower and the iron oxides (Fe2O3 and Fe3O4) coming from the top are reduced in steps to FeO. Limestone is also decomposed to CaO which removes silicate impurity of the ore as slag. The slag is in molten state and separates out from iron.Equation here for lime stone. Thus, the reduction reactions taking place in the lower temperature range and in the higher temperature rangedepend on the points ofcorresponding intersections in the ΔrG minus verses T plots. These reactions can be given as follows:At 500 -- 800 K lower temperature range in the blast furnace. 3 Fe2O3 + CO gives 2 Fe3O4 + CO2 equation 11. Fe3O4 + 4 CO gives 3Fe + 4 CO2 equation 12. Fe2O3 + CO gives 2FeO + CO2 equation 13. At 900 -- 1500 K higher temperature range in the blastfurnace:C + CO2 gives 2 CO equation 14. FeO + CO gives Fe + CO2 equation 15. The iron obtained from Blast furnace contains about 4% carbon and manyimpurities in smaller amount (e.g., S, P, Si, Mn).

Chemical Elements: http://www.ebay.com /usr/novaelementscom?_trksid=p2047675.l2559 NOVAELEMENTS: https://www.novaelements.com/ Mel Science chemical sets: https://goo.gl/SxwFlQ Patreon: https://www.patreon.com/Thoisoi?ty=h Facebook: https://www.facebook.com/thoisoi2 Interesting page about chemical experiments: http://m.chemicum.com/ Instagram: https://www.instagram.com/thoisoi/ So today I will tell you about the most rare metal on Earth - iridium. Iridium is a transitional metal, which is located in the middle of the periodic table, below rhodium. If we take a look at the prevalence of all elements in the earth's crust, Iridium holds the last place, that is a billion atoms of all that there is and only one atom of iridium. This metal is 40 times rarer than gold. In much higher concentrations iridium is found in meteorites and also in the depths of the Earth, in magma. Interestingly enough, in the layers of rock sediments, though more precisely in the formation of clay, that is aged about 66 million years there were found high concentrations of iridium and this can indicate the collision of Earth with a huge meteorite in the past, which in theory was the cause of the death of the dinosaurs. In it’s appearance iridium is a shiny metal that does not oxidize in air. This metal has almost the highest density of all metals, just 0.12% lower than that of osmium - the most dense metal. In this tiny tiny metal droplet, which is of the size of a match head, we have 1 gram of iridium. To help you understand how high is the density of iridium, I will show other metals with the same mass for comparison. Lead, copper, gallium, zinc, magnesium, and the lightest metal - lithium. The volumes of the first and last metal differ by about 30 times, although their mass is the same. Iridium is also a very hard metal that is firmer than the solid steel in 1.5 (one and a half) times. Iridium, in addition to its rarity is even the most stable metal that does not oxidize in air up to 2000 degrees, and is not soluble in either acid or aqua regia. Iridium can only react with the fluorine at temperatures of about 600 degrees. Unfortunately, due to the low activity of iridium, I cannot conduct any chemical experiments or have quality reactions with it. The only thing that I can do is make a fine powder of iridium and set it on fire in the air, but as you can see, in this case iridium dust is burning quite slowly and also requires dispersing it in the air. For the first time on youtube, you can observe a burning iridium. Also, due to the low activity of iridium, the metal does not tarnish in air, even when heated to above 1,000 degrees. The only thing that the drop of iridium got covered with is a partially evaporated ceramic layer, the one that the forceps are made from. Iridium compounds are can be either brown or yellow, such as the complex of Vasca, which is used as a catalyst in organic chemistry. By the way, Iridium is the only element that can give away 9 electrons and form compounds with +9 (plus nine) oxidation state. Iridium now finds many uses in science and technology. In most cases, we will probably find iridium in spark plugs for vehicles, due to the high stability of iridium to oxidation under the influence of electric discharge. Pure iridium is used for making crucibles for growing single crystals, foil for making non-amalgam cathodes, as well as as a part of the highly resistant to corrosion alloys. The first standard of mass of one kilogram was created in 1889 using an alloy composition of 90% platinum and 10% iridium and is called the International Prototype Kilogram, it is still kept in the Paris Chamber of Weights and Measures. Now you know more about one more of the elements, if you would like the scientific series of the elements to continue, please subscribe to my channel and also throw in some likes if you can!

Our topic for today is Electrolytic Refining of Metals. Electrolytic refining is the process of obtaining pure metals like gold, silver, copper etc. by the process of electrolysis. Let us learn how copper is refined electrolytically. Take acidified copper sulphate solution as the electrolyte. Take a thick rod of impure copper and a thin rod of pure copper. Make impure copper as the anode and pure copper as the cathode. When current is passed through the solution, the CuSO4 electrolyte splits into copper ions and sulphate ions. The copper ions from the electrolyte get attracted towards the cathode. The copper ions gain 2 electrons from the cathode and deposit as pure copper atoms on the thin copper rod. At the same time, the copper atoms from the anode lose 2 electrons, convert into copper ions and dissolve in the electrolytic solution. In this way, indirectly, copper atoms from the anode deposit on the cathode. Hence, size of anode decreases and size of cathode increases. In this way, all the pure copper from the anode deposits on the cathode. The impurities in the impure copper rod settle down as anode mud at the bottom of the container.

So, today I want to tell you about the hardest metal on Earth – chromium. As usual, let's first see where chromium is in the periodic table of chemical elements. Oh, there it is, hiding behind the vanadium in the 6th group. And yes, I did not deceive you, it is true that chromium has the highest hardness of all metals, based on the Mohs scale that shows the resistance of a mineral to scratching. Externally, pure chromium is a lustrous white metal that does not tarnish in air. To demonstrate the main feature of chromium, namely its topmost hardness, I will scratch an ordinary silicate glass with it. As you can see on this chart, the hardness of the glass is much smaller. As usual, you cannot fool physics, chromium easily scratched the surface of the glass, leaving a clearly discernible markings. Although, I think that the hardness of chromium is very much dependent on its purity. Metallic chromium is obtained from the chromium ore mineral by reducing it using carbon to produce ferrochromium, an alloy of chromium and iron, which is used in production of stainless steel. We will now turn to the chemical properties of chromium which this metal is highly enriched with. The fact is, even the name of the metal, chromium, comes from the Greek "khroma" meaning color. This name came to pass due the fact that chromium compounds can have almost all the colors of a rainbow. In a laboratory the most common chromium compound is potassium dichromate. It is used often in analytical chemistry, or to clean chemical dishes from the very stubborn dirt. Also, this substance is used as an intermediate compound in the production of chromium metal from ore. In this compound chromium has an oxidation state of plus six. By the way, if you mix the potassium dichromate with any reducing agent, for example aluminium powder, and then ignite it, you will see a very violent reaction that will produce particles of chromium metal. Potassium dichromate is very soluble in water. If you add a little bit of alkali, i.e. sodium hydroxide, to the orange solution of potassium dichromate, in an alkaline environment the dichromate will turn into chromate, and become yellow. In the oxidation state of plus six, chromium may have a yellow and an orange color, depending on the acidity of the environment. However, that's not all. If you add acid to the solution of potassium dichromate and also any reducing agent, for example potassium metabisulfite, there will be a reaction in which sulfur from metabisulfite will donate electrons to chromium, and will be restored to its trivalent state, therefore changing its color to green. Compounds of trivalent chromium have a green color, this is possible to prove with another reaction. In order to do it, let’s take another orange chromium compound - ammonium dichromate, in which chromium also has an oxidation state of plus six. Now I’m igniting this orange powder and what do we see? Ammonium dichromate started decomposing by itself, forming a dark-green substance – chromium oxide.

Aluminium is the most abundant metal on Earth. However, it is expensive because a lot of electricity is used to extract it. Bauxite is the aluminium ore. It is purified to yield aluminium oxide, which is a white powder. Aluminium is then extracted from aluminium oxide by electrolysis. The aluminium oxide must be made molten so that the ions can pass through it during electrolysis. Aluminium oxide has a very high melting point - over 2000 degrees celsius. So instead of trying to melt it, the aluminium oxide is dissolved in molten cryolite. Cryolite is an aluminium compound with a much lower melting point than aluminium oxide, and so using this reduces some of the costs in extracting aluminium. The steel case is coated with graphite, providing the negative cathode. The positive anodes are immersed in the molten cryolite, and are also made of graphite. When the battery is turned on and electricity flows, the aluminium forms at the negative cathode and sinks to the bottom of the tank where is is tapped off as a pure liquid metal. Oxygen forms at the positive anodes. The oxygen reacts with the carbon of the graphite, forming carbon dioxide. The positive anode therefore burns away, and needs replacing regularly. This is another reason for the extraction of aluminium being so expensive. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

Whenever energy in any form penetrates rock, ore or mineral, wear will appear also new sensors have been developed which exploit material properties such as electrical conductivity, magnetization, molecular structure and thermal conductivity. Almost all earth materials are used by humans for something. It is also used if ores are not locally concentrated but spread over a wide area. The ores are extracted from the earth through mining; They then refined (often via smelting) to extract valuable element, or elements. The size of the ore bed increases as mining continues, and eventually, pit becomes a very large bowl shaped hole in earth's surface. Unit 3 reading mining and impacts serc carletonintroduction to.

This process is not only cool to look at, but it also is really useful to extract gold from ore. The gold-mercury amalgam can then be isolated and the mercury is boiled off or removed chemically. This leaves behind relatively pure gold. Outro music: https://soundcloud.com/sorrysines

Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today. This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment. The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.

It is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and named by Martin Heinrich Klaproth for the Titans of Greek mythology. The element occurs within a number of mineral deposits, principally rutile and ilmenite, which are widely distributed in Earth's crust and lithosphere, and it is found in almost all living things, rocks, water bodies, and soils. The metal is extracted from its principal mineral ores via the Kroll process or the Hunter process. Its most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and titanium trichloride (TiCl3), which is used as a catalyst in the production of polypropylene. Titanium can be alloyed with iron, aluminium, vanadium, and molybdenum, among other elements, to produce strong, lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial process (chemicals and petro-chemicals, desalination plants, pulp, and paper), automotive, agri-food, medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, mobile phones, and other applications. The two most useful properties of the metal are corrosion resistance and the highest strength-to-density ratio of any metallic element. In its unalloyed condition, titanium is as strong as some steels, but less dense. There are two allotropic forms and five naturally occurring isotopes of this element, 46Ti through 50Ti, with 48Ti being the most abundant (73.8%). Although they have the same number of valence electrons and are in the same group in the periodic table, titanium and zirconium differ in many chemical and physical properties... About 95% of titanium ore extracted from the Earth is destined for refinement into titanium dioxide (TiO2), an intensely white permanent pigment used in paints, paper, toothpaste, and plastics. It is also used in cement, in gemstones, as an optical opacifier in paper, and a strengthening agent in graphite composite fishing rods and golf clubs. TiO2 powder is chemically inert, resists fading in sunlight, and is very opaque: this allows it to impart a pure and brilliant white color to the brown or gray chemicals that form the majority of household plastics. In nature, this compound is found in the minerals anatase, brookite, and rutile. Paint made with titanium dioxide does well in severe temperatures, and stands up to marine environments. Pure titanium dioxide has a very high index of refraction and an optical dispersion higher than diamond. In addition to being a very important pigment, titanium dioxide is also used in sunscreens due to its ability to protect skin by itself...

We are excited to post this video and show you all our progress on processing printed circuit boards (PCB's) for gold, copper and other metals with our hammer mill and shaker table. We have the ability to take whole boards, crush them, and run them on our shaker table. We are still in the experimental stage but we have high hopes to have a complete system ready to sell soon. I should clarify that we can't recover all the gold from the boards, but at the end of the video we do have free metallic gold in the gold pan. Our goal is to take whole boards and concentrate out the valuables (metals) from the non-values (fiberglass, plastic, etc). The free gold can easily be removed, melted, and sold directly to a gold buyer, leaving the concentrates, which are much more valuable that the boards themselves. The remaining gold is plated onto other metals. This cannot be mechanically separated, but using the hammer mill and shaker table it can be concentrated into a salable product. The #2 and #3 hole outputs can be sold to a refiner and let them deal with all the chemicals and refining process. For most people its too complicated, dangerous, expensive, etc. to separate out the different metals in the concentrates. As a side note the free gold per pound recovered from the ~20 pounds of boards equates to 1 troy ounce per ton of boards. This would be considered very high grade gold ore for any miner. The PCB's also have loads of copper, tin, lead, plated gold, etc that is added value on top of that 1 oz/ton free gold recovered.

Aluminum (also called Aluminium) the chemical element of atomic number 13, symbol of Al. It belongs to the group 13 of the periodic table and the poor metals family. The simple aluminum body is a malleable metal, silver in color, noted for its resistance to oxydationnote 1 and its low density. This is the most abundant metal in the earth's crust and the third most abundant element after oxygen and silicon; it represents on average 8% of the mass of material of the solid surface of our planet. Aluminium is, in general, too reactive to exist in the native state in the naturelnote 2 medium: it is found on the contrary in combined form in over 270 different minerals, its main ore is bauxite, where it is present in the form of hydrous oxide of which alumina is extracted. It can also be extracted from nepheline, leucite, sillimanite, andalusite and muscovite.

Although it is a precious mineral resource, rare earth imposes great dangers of pollution. Recently, French media reported from Baotou. Entitled "In China, rare earths are killing villages", the report highlighted massive environmental pollution. It revealed the impact of the production of rare earth minerals on local residents, animals and land. The following is our report. French media 'Le Monde' reported from Baotou, stating that by aerial viewpoint, it looks like a large lake, fed by numerous tributaries. On site, it is actually an opaque discharge covering an area of 10 km2. Surrounding the industrial plants producing 17 minerals are reject waste waters loaded with chemicals. There are no fish or algae The Le Monde article introduced that rock from Bayan obo rare earth ore mine, located 120 kilometers away, are sent here for treatment. The concentration of rare earth in the rocks is very low and must be separated and purified by hydrometallurgical processes and acid baths. In the effluent basin are exist all sorts of toxic chemicals and radioactive elements such as thorium. Ingestion of these toxins causes cancer of the pancreas, lung and blood. A pungent odor exudes within radius of 10 miles. Local villagers have been suffering from cancer. Rows of brown houses in the village have been reduced to rubble. Sichuan environmentalist Chen Yunfei indicates that rare earth refining process causes great environmental pollution and destruction. People are unaware of the specific dangers of this project, and the specialists involved in the decision-making. Chen Yunfei: "Some officials only work on the image projects for profit. They relocate once the money has been made. Some officials collude with the business, caring about nothing but profit, leaving the mess for the public." According to local residents, Baotou used to be a vast grassland. In 1958 the state enterprise Baotou Iron and Steel Company began producing rare earth production. By the end of 1980, locals found that the plant was in trouble. Last year, China Environment News reported that Baotou Iron and Steel Group's tailing dam leakage has caused damage to five surrounding villages. It has affected more than 3000 farmers, and ruined more than 3,295 Acres of farmland. Ma Peng, former Director of the Baotou Rare Earth Research Institute, indicated that due to the lack of a barrier below the tailing dam, the mining waste is directly discharging into the Yellow River. The discharge is at a rate of 300m per year. The residents also said that further pollution has been caused by other industries and thermal power plants. These industries followed rare earth production by the Baotou Iron and Steel Company. Local residents have to breathe air saturated with sulfuric acid and coal dust. Coal dust is airbourne around the houses. Cows, horses, chickens and goats are being killed by these poisons. The locals have fled, and Xinguang Sancun village has now decreased from 2000 villagers to 300. Every family is hit with illness. After 20 years of complaints to the local government, the villagers have finally won promises of financial compensation. These have only been partially fulfilled. Miss Hao, a resident of Baotou: "We all know. The government is too dark. No one cares about the people, whether they live or die, not to mention the pollution." For many years, there have been calls for attention for the issue of Baotou tailing dam discharging thorium radiation to Baotou and into the Yellow River. The hazards and pollution caused by the Baotou tailing dam have never been effectively alleviated. Environmentalist Chen Yunfei: "This is an investment that has hurt several generations. It has polluted the whole environment. This high cost investment ought to be condemned. Our future generations are going to suffer for it." China Environment News indicated that Baotou is located in the stratum fracture zone. In the event of a major earthquake or large-scale rainfall, the rupture of the tailing dam will threaten the surrounding five villages, as well as tens of thousands of lives of the Baotou Iron and Steel workers. If the tailings flow into the Yellow River, it will cause serious pollution to the river. 《神韵》2011世界巡演新亮点 http://www.ShenYunPerformingArts.org/

They find out that mineral compounds combine to form different types of rock and that these minerals are unevenly distributed within rock. Minerals are defined as inorganic substances with a definite chemical composition. The learners discover that by observing a sample of rock they can analyse its components and develop insight into how it was formed. The lesson also investigates the history of our ability to extract metals from ore; this is closely related to our capacity to harness fire.

Animation of atomic bombs: https://www.youtube.com/channel/UCocSPp2haPIl0_edFrDimPw Hi everyone! I guess you have figured that this video is going to be about such a metal as uranium. However, let me make give a small warning in order to calm you down. I think now we have settled everything and can move on to considering properties of the most dangerous metal on earth - uranium. Uranium belongs to the actinides series in the periodic table that is to radioactive elements and its atomic number is 92. Uranium is 40 times more abundant in earth’s crust than silver. It forms in abundance upon rapid neutron capture inside spinning supernovas. That is why uranium was discovered quite early, in Germany in 18-th century. Its discoverer, Martin Heinrich Klaproth, named it after a newly discovered planet of the solar system, after Uranus. In nature uranium is often found in such minerals as uraninite and autunite. This metal often has several oxidation states in those minerals. Thanks to the beautiful yellow colour of such minerals, glass blowers added them to glass. As a result minerals would give such glass a beautiful greenish colour. It’s a pity that back then craftsmen didn’t not about the toxicity of uranium compounds. Nevertheless, pure metallic uranium can be obtained from uranium ore via reduction by calcium which looks very ordinary. Since mostly uranium naturally occurs in the form of uranium-238 isotope with a half-life of about 4.468 billion years, in 99, 23% of cases to be precise. Depleted uranium is most frequently used for chemical researches, that is uranium-238, in order to reduce scientists’ exposure to its radiation. Also there are only two radioactive metals that occur naturally. Those are uranium and thorium. It’s so because of their extremely long half-lives. Pure uranium obtained from its ore looks quite dark as its surface oxidizes pretty fast because of the high chemical activeness of this metal. That is why it is often stored in argon and also all experiments with uranium are conducted in argon medium. Usually a piece of pure metallic uranium-238 is ripped to such small shreds on a lathe in a laboratory. It is noteworthy that these shreds in the test tube already emit beta and gamma radiation.

Mineral Jigs: https://www.savonaequipment.com/en/equipment/gold-concentrating-refining/gold-concentrating-tables-e41438 Mineral jigs are a type of mining equipment, also referred to as gravity concentrators or jig concentrators, that are used in operations to separate different ore materials based on their densities. Usually they will process material that is a similar size after the ore has passed through a crusher or over a screening plant. Although there are many variants that will take place in a mineral jig, certain principles remain constant. Material is first fed into the jig bed, usually made with a screen, then propulsing columns thrust water upward which suspend particles in the water because they have been exposed to gravitational energy. Frequencies normally range in between 125-350 strokes/minute. In between the pulses material that is heavier will be trapped in the bed filled with steel shot (small round steel media) and settle in the bottom of the jig and the concentration is removed separately for further processing with an example being over a gold concentrating table or if the grade is high enough in a smelting furnace. If a jig concentrator is being used for minerals that are lower in density, coal being one, the gravitational energy has a reverse effect because material around coal is heavier and the coal will float towards the top. #savonaequipment #miningequipment #goldrecovery #mining ♦️Grinding MIlls: https://www.savonaequipment.com/en/equipment/mills-grinding-mills-e41552 ♦️Gold Concentrating & Refining: https://www.savonaequipment.com/en/equipment/gold-concentrating-refining-e41436 ♦️Steel Media: https://www.savonaequipment.com/en/equipment/mills-grinding-mills/grinding-media-e64499
