Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.

Cyanide Leaching Chemistry & Gold Cyanidation

The net result is the complication of the chemistry involved in the cyanide process. Compare Cyanide VS Thiosulphate gold Leaching. No two ores are exactly alike. Therefore, it is practically impossible to predict how an ore will act during cyanidation, although broad generalizations can sometimes be made.

Process of Cyanide Gold Extraction

Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high-lime solution prior to cyanidation. It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 0.3 to 0.7% ...
