The Goldmine

Product Information

Many conservationists and community opposition groups see gold mining as a battle between nature and greed, and question whether the pursuit of gold is really worth so much environmental destruction. So does Baur, the financial economist, who says it makes sense from both an environmental and economic perspective to just not mine for gold at all. Much of the gold that already exists aboveground, he says, is held by banks and investment companies. Investors can buy shares of gold they’ve never even seen. Baur says that they might as well just buy shares of gold that companies promise to leave in the ground. “You buy something that doesn’t disrupt the land as much,” he says, “and you don’t have all the negative effects of the actual gold mining.” Ali, Saleem H. (2006), "Gold Mining and the Golden Rule: A Challenge for Developed and Developing Countries", Journal of Cleaner Production, 14 (3–4): 455–462, doi: 10.1016/j.jclepro.2004.05.009 Using a sluice box to extract gold from placer deposits has long been a very 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 volt where gold and other dense material settles out behind the riffles. Less dense material flows out of the box as tailings. in the world. The smaller geographic size of the UK leaves little area for large-scale mining operations.

The mining of the Hungarian deposit (present-day Slovakia) primarily around Kremnica was the largest of the Medieval period in Europe.

Landscape of Las Médulas, Spain, the result of hydraulic mining on a vast scale by the Ancient RomansKitco News) - Kitco ranked the world's biggest gold mines by production in 2020. The ranking below was developed on the basis of 2020 (calendar year) production figures reported by companies and preliminary estimates for Muruntau. Gold output is in thousand ounces (koz). Scotgold Resources, which declared in late September that it had put the majority of its 80-strong workforce at the Cononish mine near Tyndrum on unpaid leave, had said on November 7 it was “considering the appointment of administrators over the coming days”.

Deposits of gold come in either ‘lodes’ – underground veins – or in ‘placers’, which are particles that have been eroded from their original lode over long periods. Gold can be extracted by either mining these lodes, or by discovering placers amongst other materials. Luke Davies works at the Exchange hotel and Goldfields Motor Inn in Blayney, where rooms have been rented out to Cadia on a two-year contract. He is anticipating hiring further staff once construction begins on the McPhillamys mine. a b "Women die in Ghana mine collapse". BBC News. 12 November 2009.

However, the metal’s chief role as an investment commodity is what makes it — and by extension, gold-mining shares — such a divisive asset class.

Retrieved 3 April 2015.Underground mining operations also intersect with the water table, which means the existing tunnels have to be dewatered, and the water that’s pumped out of the tunnels has to be treated before it’s released aboveground. “The water coming from these mines that they’re dewatering is full of arsenic, manganese, iron, and other heavy metals,” says the biologist Josie Crawford, the executive director of the Wolf Creek Community Alliance, another local group that opposes the mine. “It will be treated, but it needs to be treated forever.” During the 19th century, numerous gold rushes in remote regions around the globe caused large migrations of miners, such as the California Gold Rush of 1849, the Victorian Gold Rush, and the Klondike Gold Rush. The discovery of gold in the Witwatersrand led to the Second Boer War and ultimately the founding of South Africa. Gold-bearing reefs in the neighbouring Free State province were found shortly thereafter, driving significant development in the region with the establishment of the Free State goldfields.
