It portrays how over the last 150 years mining has made Australia rich, yet created an unending struggle over who shares in the wealth. It reveals how mining helped forge democracy yet has repeatedly plotted to influence politics and even overthrow democratically elected leaders. Whilst mining has also been deeply damaging to Aboriginal society, ironically in the 21st century, it may be aboriginal people's best hope of economic self-determination.

National Geographic Megastructures - the World s Deepest Gold Mine | BBC Documentary History ⏩⏩⏩ SUBSCRIBE to : https://goo.gl/89mjhF National Geographic Megastructures Megastructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia. Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products. Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases (such as the Akashi-Kaikyo Bridge and Petronas Towers) this involved the development of new materials or products that are now in general use within the construction industry. Megastructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first (such as Dubai's Palm Islands). This type of project is known as a megaproject. The series follows similar subjects as the History Channel's Modern Marvels and Discovery Channel's Extreme Engineering, covering areas of architecture, transport, construction and manufacturing. National Geographic (formerly National Geographic Channel and also commercially abbreviated and trademarked as Nat Geo) is the American digital cable and satellite television channel that is owned by National Geographic Partners, majority-owned by 21st Century Fox with the remainder owned by the National Geographic Society.

$400 Million Emerald Mystery It has a complicated and unfathomable history - will the authorities ever find an owner for the Bahia Emerald -- or will it prove just too powerful to shift? Find out in $400 Million Emerald Mystery and explore the gemstone's colourful history and analyse the different claims over it. The unearthing of what may be the world's largest emerald in Brazil is a truly remarkable story, but the staggering eight-way battle for its ownership is almost too astonishing to believe. Found in a Bahia mine in 2001, the remarkable stone, valued at $400 million, has since endured a bizarre odyssey, from an abandoned petrol station in San Jose to a submerged vault in Hurricane Katrina-ravaged New Orleans. With the gemstone trade a world of mystery and intrigue, the 840lb (381Kg) specimen has already changed hands in a Sao Paulo car park, been used as collateral in a diamond deal and even shown up on eBay!

Our world produces some incredible rocks. Take the opal, a precious stone that forms out of silica, in the dark under the surface of the earth. When cut and polished, it flashes with a gorgeous array of colours, from pale milky hues to deep reds and blacks. Now, an opal that has been named the finest ever unearthed will be making its public debut next month as the centrepiece of an exhibition opening at the South Australian Museum, Adelaide. Called the Virgin Rainbow, it was discovered in the opal fields of Coober Pedy by opal miner John Dunstan in 2003. It's actually an opalised fossil, from an extinct cephalopod called belemnitida that existed during the Mesozoic era. During that time, much of South Australia was under a vast inland sea filled with prehistoric aquatic reptiles called plesiosaurs. These died and sank to the bottom of the sea, buried over the millennia by sediment. When the sea dried up and the land turned into a desert, the acidity levels in the shallow top layer of the sandstone increased. This released silica from weathering sandstone into the layer of clay beneath, where bones and pockets left by disintegrated bones lay buried, carried down via groundwater. Further weathering lowered the acidity levels, which allowed the silica gel to harden into opals in the pockets and impressions left by decayed animal material, like cake poured into a mould, or to soak into bones and create a replica of the internal structure. The famous Australian opal fields of Coober Pedy are located in this region. No other environment in the world is known to have undergone this same process, which is possibly why over 90 percent of the world's opals come from South Australia. SUBSCRIBE

With shocking evidence now uncovered, Zimbabwe's diamond trade faces suspension. "We were told here are the guns, sitting in the truck, do you want to stay?" says Andrew Cranswick, CEO of the mining company who owns the rights to mine diamonds in Marange. After his company was evicted, the Marange fields were opened up to the people and tens of thousands of Zimbabweans came to dig, paying the police a commission. Yet the police didn't always play fair - "$15 million worth of diamonds were confiscated", says one former miner and soon the police were replaced by Mugabes own military. "Mugabe needed a way to buy the loyalty of the army" says Ken Roth, "the military were ordered to kill". In the first week of November, helicopter gunships launched a massacre on the Marange diamond fields. Evidence has been collected of 200 deaths. Those who weren't killed were raped or crippled. "They told us if we wanted to go home we had to sleep with the men", says one woman, "the soldiers watched and laughed". Next month, the Kimberley process, the international body charged with stopping trade in conflict diamonds, will decide whether Zimbabwe should be suspended. Yet with many Western governments involved in Zimbabwe's diamond trade, a former delegate of the Kimberley process believes this deadly business may yet be protected.

He's a Frenchman who first came to Afghanistan to train Afghan security services before venturing into the emerald trade. He sees a huge chance here to exploit a market that could easily increase in value twenty or thirty-fold, but the obstacles are not inconsiderable. Just to get to the mines Raphael has to travel the 150 Kilometres from Kabul to Panjshir, right through Taliban kidnap country. When he gets there he finds an industry in the dark ages, where homemade pyrotechnics are exploded in poorly dug mineshafts, killing many miners and ruining the quality of up to 75% of the stones they dig. "If you see the damage being done to these stones... so much is lost", Yama Torabi from Integrity Watch Afghanistan tells us. The government here remains hopelessly out of touch with the industry that "still (uses) a mining law adopted 100 years ago". But as the country prepares for elections and Europeans like Raphael open up the gem trade here, could this be a beacon of hope for the future?

From the most beautiful stones in the world to the most expensive rocks you’ve ever seen these gemstones are worth a shocking amount of money 8. Ruby Rubies come in vibrant shades of dark red, bright red, and purple-red. Like diamonds, they are found globally except for Antarctica. The most valuable of these gemstones come from Asia, and its main exporters are Sri Lanka, Thailand, and Myanmar. The "pigeon's blood" varieties that spot a pure red and violet gue are by far the most popular. A ruby can go for about $15,000 in the world market because of their limited numbers. 7. Rough Diamond The most desirable of all gemstones is a rough diamond, and it also happens to be amongst the most expensive. The wedding industry could be blamed for the enormous popularity of cut diamonds globally. Besides that, most women wouldn't mind adding a jewelry piece carrying diamonds to her collection. Presently, perfectly cut D color diamonds can fetch as much as $15,000 per carat. 6. Serendibite The extremely rare gemstone originally came from Sri Lanka in 1902. The inosilicate features a complex chemical formula and comprises of aluminum, magnesium, calcium, and boron. One of these gemstones recently came out of the Mogok mines in Myanmar. The serendibite goes for $18,000 per carat. 5. Jadeite The Jade's most beautiful and rarest stone just so happens to also be the most expensive. It has been mined in a variety of colors, but its rich-emerald color continues to be the most favored, and these jadeites originate from Myanmar. However, mauve, apple green, and lavender jadeites are also quite popular with buyers. The stone also forms an integral part of the Mesoamerican, Maori, and Chinese cultures where they are used to carve weapons, fashion jewelry, and also used for medicinal and religious purposes. Jadeites are currently priced at about $20,000 per carat. 4. Grandidierite The greenish-blue or yellow-blue mineral is quite rare and was first discovered in Sri Lanka. However, in the twentieth century, Alfred Grandidier, a French explorer, found a bulk of the minerals in Madagascar. Only about two dozen of the faceted grandidierite exist today. The stone borrowed its name from its founder. The unique gemstone goes for $30,000 per carat. 3. Red Diamond Considered the most expensive gem in the world, the red diamond would set you back US$1 million per carat. In the history of mankind, very only 30 samples of these gemstones have been found, and most weigh under 0.5 carats. Australia's Argyle diamond mine is the only place where these diamonds can be mined, and only a few stones are extracted from it each year. While most people might assume that the red color is an impurity, it comes from the deformation of the crystal lattice. The priciest and largest of these stones ever sold was the Moussaieff Red Diamond that went for $8 million in 2011. 2. Blue Diamond Colored diamonds tend to be amongst the most expensive gemstones in the world because of their rarity and spectacular brilliance. Colored diamonds occur in a spectrum of black, yellow, champagne, red, chocolate/brown, pink, green, and blue colors. The most popular are the Pink Star and Oppenheimer Blue. The Oppenheimer Blue diamond has a vivid blue hue and its the largest of such diamonds to go on auction selling for $57.5 million. That particular piece weighed 14.62 carats translating to $3.93 million per carat. The Pink Star recently broke the record selling for a whopping $71.2 million for a 59.6-carat piece. 1. US$3 Million Rare Black Opal Bobby, an Australian miner, found an opal back in 2002. After he fell on hard times, he sold his mining equipment and took home his last bucket of rocks. He began rubbing the grimy stones and discovered hints of gold and green. It took Bobby two years to whittle the encasing rock away from the gemstone hidden inside. What he ended up with was an extremely rare 306-carat black opal. You'd think that he would cash in on the precious stone, but instead, he kept it tucked safely underneath his mattress for another 12 years. It kind of reminds you of a certain character from The Lord Of The Rings, and Bobby himself said that he considered it one of God's greatest creations that he had to guard. He finally entrusted it to Katherine Jetter, an Australian jewelry designer who debuted it at a Wynn Hotel, Las Vegas Couture show for US$3 million. The black opals generally sell at $3,500 per carat. Thanks for watching coming up next Insane Military Tech and Machines That Actually Exist!

South Africa's TauTona mine, real life alchemy, and Halicephalobus Mephisto. Footage from the 2012 documentary, "Down to the Earth's Core". We have travelled into space and looked deep into the universe's depths, but the world beneath our feet remains unexplored and unseen. Now, that's about to change. For the first time in one epic unbroken shot, we embark on an impossible mission - using spectacular computer generated imagery to smash through three thousand miles of solid rock, and venture from our world into the underworld and on to the core of the Earth itself. It's a journey fraught with danger. One thousand feet down we find ourselves inside one of the planet's most volatile places - the San Andreas Fault. Caught between two huge rock slabs, we watch as stress builds and then releases. It unleashes an earthquake and blasts us on towards rivers of molten rock, explosive volcanoes, tears in the Earth's crust and giant tornadoes of liquid metal. But for every danger, there are wonders beyond imagination. Four hundred feet below the surface, a three hundred million year old fossilized forest, with every leaf and every piece of bark perfectly preserved. At one thousand feet down we enter a cave of giant crystals, glistening in deadly 122 degree heat. More than two miles underground we find buried treasure - gold and gems. Deeper still there are valuable resources - salt, oil, coal and iron. And over one hundred miles down we see the sparkling beauty of diamonds. As we descend we piece together our planet's extraordinary story. We rewind time to discover how prehistoric forests became modern-day fuel. 1700 feet down a layer of rock reveals the extraordinary story of the dinosaurs' cataclysmic death. We watch stalactites form and gold grow before our eyes. The deeper we travel into the underworld the more we understand our world above the surface. A bigger picture takes shape - a cycle of destruction and creation, driven by the core that sustains our dynamic planet and makes the Earth the only planet with life in a seemingly lifeless universe. Until, finally, three thousand miles down, we reach the core. Inside it lie the secrets of life as we know it - the magnetic force field that protects life on Earth from the sun's deadly rays, the ancient heat source that keeps our planet alive. Down to the Earth's Core brings the latest science together with breathtaking computer generated imagery. The result is an unmissable journey into an extraordinary world - full of dangers, wonders and secrets. And it's all down there, beneath our feet, right now waiting to be discovered.

Diamond Mining - How are diamonds mined and formed? Documentary Film In mineralogy, diamond is a metastable allotrope of carbon, where the carbon atoms are organized in a variation of the face-centered cubic crystal structure called a diamond lattice. Ruby is less secure than graphite, yet the conversion rate from ruby to graphite is negligible at typical problems. Diamond is renowned as a material with outstanding physical high qualities, the majority of which stem from the strong covalent bonding between its atoms. Specifically, ruby has the highest solidity and thermal conductivity of any type of mass material. Those properties figure out the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond blades and ruby anvil cells. As a result of its exceptionally stiff lattice, it could be polluted by really few kinds of contaminations, such as boron and nitrogen. Percentages of defects or impurities (concerning one per million of lattice atoms) shade ruby blue (boron), yellow (nitrogen), brownish (lattice problems), environment-friendly (radiation direct exposure), purple, pink, red or orange. Diamond also has reasonably high optical dispersion (ability to disperse light of various colors).

More films about the Philippines: https://rtd.rt.com/tags/philippines/ - The use of child labour in the Philippine’s Paracale, or ‘Goldtown’, is widespread - Extracting gold involves diving into mud-filled shafts and using toxic mercury - Poverty and lack of alternative jobs force people into this highly dangerous work - Many die young due to work accidents or breathing problems, others develop chronic illness The Philippines’ town of Paracale was dubbed “Goldtown” for its rich deposits of the precious metal. Despite government attempts to regulate mining, illegal pits are still commonplace. They lack even the most basic health and safety and workers are exposed to toxic mercury fumes. Dirty water causes skin diseases and they live with the constant threat of being buried alive. Workers continue to take these risks day after day, because there is no other source of income. Many of the gold miners are children whose families can’t afford to send them to school. Some gold is panned on the surface, but a lot has to be extracted from underground. To do that, prospectors dive into narrow, mud-filled shafts, uses snorkelling masks and long tubes too breathe. If the mine collapses, they have no chance of escape. They have a saying here, ‘while you’re down the mine, you have one foot in the grave’. Several miners have already died that way, others from respiratory diseases caused by inhaling mercury fumes. The toxic metal is used in gold extraction with no safety precautions, so it poisons the air, the ground and the water, causing long-term harm to the whole community. Another danger to the inhabitants of Paracale comes from disused mines, abandoned and left open, waiting for unsuspecting victims to fall in. The business takes its toll on workers, their families and the community. They have been known to demonstrate, demanding safer working conditions, better pay and other job opportunities, but change is slow. Meanwhile, extreme poverty among people who produce one of the world’s most precious metals leaves them no option but to continue with this pitiless occupation.

Gold Dust: Under Blaise Compaore's leadership, Burkina Faso's unregulated gold rush has had a devastating effect on mining conditions. This report digs deep into the industry, exposing the corruption beneath Compaore's ruling. Millions of people - including children as young as fourteen - mine in an unregulated industry for a few golden grams of hope. Marcel toils underground to support his family - but without the glittering rewards promised. “We all have hope, we hope to earn” he says, but "they rob us here...They treat the miner like an animal." 17-year old Soumaele has been mining for two years. His thin body can go to even deeper than the older men, to places where the air is impossible to breathe and the tunnels are likely to collapse. Gold promises a great deal, but in an anarchic industry, teacher Soungalo Hema fears for the future of children like Soumaele: "You try and save them", she says, "but a lot of the time it’s in vain. I ask myself 'what will happen to all of us?'"
