Finding Valuable Gold Ore in Mines

The reality of just how much that ore weighs sinks in. Gold is priced at 19 per troy ounce and even a high-grade ore may take a few tons to produce once ounce of gold. The miner takes his ore into town. It needs to be crushed and processed but he doesn t have a stamp mill so he contracts the work to a nearby mine that has gold.

GOLD MINING IN SOUTH CAROLINAcecas.clemson.edu

 · Cyanide is the most popular chemical used by mining corporations to extract gold from ore despite the fact that leaks or spills of this chemical are extremely toxic to fish plant life and human beings. The term "cyanide" refers to numerous compounds both natural and human-made having the chemical group CN that is one atom of carbon and one atom of nitrogen. Cyanide combines with up to 97 of gold including particles of gold that are too small to be seen by the naked eye making it one of the most efficient process chemicals for the extraction of the metal. Cyanide leaching involves spraying a sodium cyanide solution (at 250 to 500 parts per million) on finely ground ore or on old waste rock known as tailings. The gold forms a water-soluble chemical compound with the cyanide which is then run over activated carbon to extract the gold. The cyanide waste that is left over is supposed to be stored in lined and covered ponds to prevent contact with local animals and birds. Some companies process the ore in vats allowing the cyanide
