Potassium Cyanide In Gold Mining

Effect of Potassium Cyanide on Gold & Metals

The discovery that metallic gold is soluble in potassium cyanide came after studying the action of cyanides on plates of gold, and announced that they were slowly dissolved. Metallurgists pointed out that gold-leaf is dissolved by a dilute solution of the salt, and also showed that if the gold floats on the surface of the liquid, so that one side of the leaf is in contact with the air, while

Potassium dicyanoaurate Wikipedia

Potassium dicyanoaurate, also potassium dicyanoaurate(I), potassium gold cyanide, potassium gold dicyanide or gold potassium cyanide, is an inorganic compound with formula K[Au(CN) 2].It is a colorless to white crystalline powder, usually prepared by dissolving metallic gold in aqueous solution of potassium cyanide.It is most often used in gold plating applications.

Cyanide Use in Gold Mining Earthworks

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;

BACKGROUND NOTE ON CYANIDE IN GOLD MINING

hydrogen cyanide gas and the simple cyanide salts (sodi um cyanide and potassium cyanide), can occur naturally or be man-made and many are powerful and rapid-acting poisons. The predominant users of cyanides are the steel, Cyanide use in mining Gold typically occurs at very low concentrations in ores less than 10 g/ton.

CYANIDE AND CYANIDE COMPLEXES IN THE GOLD- MINE

The use of sodium, potassium or calcium cyanide in the gold mining industry poses a potential environmental threat. Cyanide is a very poisonous substance which may infiltrate water sources or escape into the air. Thus it may be inhaled by human beings, drunk if it gets into the potable water system, or may enter the food chain unobtrusively.

Cyanide Hazards to Plants and Animals From Gold Mining

Cyanide extraction of gold through milling of high-grade ores and heap leaching of low-grade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (NaCN), free cyanide, and metal-cyanide complexes.
