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. The important environmental problem is theSeveral of the gold salt sources used are potassium gold cyanide, gold chloride, and gold sulfite. By far, potassium gold cyanide is the most common source. 37 Because the gold solution normally contains cyanide compounds, extra precaution is needed in the process and waste treatment of the plating solutions. 12,19 The reducing agents used are also as diverse as the gold source, such asGold Plating an overview | ScienceDirect Topics15/02/2009· a. how to produce potassium gold cyanide b. uses of potassium gold cyanide c. cost per gram Thank you very much.

How is cyanide used in gold mining? Quora

Cyanidation is used to extract gold from a finely ground ore material in a mix with water at about 55% solids by mass. Gold extraction is always a surface processing based extraction process and has nothing to do with the process of Mining itself....Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide. Almost 90% of all gold extracted commercially is done so by cyanidation. The process has beenWhat is Gold Cyanidation? (with picture) Info Bloom
