COMPARISON OF CYANIDE AND THIOSULPHATE LEACHING FOR GOLD .

Gold cyanidation is the main gold leaching process and it has been used over century. Cyanide is relatively low cost and effective lixiviant for gold dissolution; gold is dissolved in a very dilute solution of sodium cyanide (NaCN). The main concern of cyanidation is its high toxicity.

Gold extraction - Wikipedia

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic ...
