Although "cyanidation"—the use of a sodium cyanide compound to separate a precious metal from finely ground rock—has become less common in other forms of mining, it is still the dominant practice in gold mining. Some 90 percent of gold mines around the world employ cyanidation to harvest their loot.
Gold Mining with Cyanide Some 90 percent of gold mines around the world employ "cyanidation," the use of a sodium cyanide compound to separate the gold from finely ground rock. At a gold mine in Romania in 2000, the accidental release of 100,000 cubic meters of cyaniderich waste into the local watershed killed all aquatic life in nearby waters
Sodium cyanide CAS No: 143339. The National Industrial Chemicals Notifiion and Assessment Scheme (NICNAS) has assessed the environmental risks of sodium cyanide and made recommendations for reducing the risks from its transport and use in mining. The final report is available on the NICNAS website.
For example, gold forms a covalent bond with a cyanide ion, which is why cyanide salts are used in the mining industry. Is Cyanide is historically found in Gold and silver mining operations? No.

Sodium cyanide is an inorganic compound with the formula Na C N.It is a white, watersoluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main appliion, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:
Cyanide is manufactured and distributed for use in the gold and silver mining industries in a variety of physical and chemical forms, including solid briquettes, flake cyanide and liquid cyanide. Sodium cyanide is supplied as either briquettes or liquid, while calcium cyanide is supplied in

Sodium Cyanide in Gold Mining is a health risk. According to reliable reports from Kakamega County, use of sodium cyanide in gold mining is a great health risk. This is a great health hazard and should be stopped immediately. Sodium cyanide is an inorganic compoundwith the formula Na C N. It is a white, watersoluble solid.
How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap.
