gold processing cyanide leaching

During the cyanide leaching process, it can undergo complex reaction with cyanide CN- under the action of oxygen to produce water-soluble cyanoaurate complex AuCN 2- Therefore, the amount of cyaniding agent is one of the key factors that determine the dissolution of gold.

A key operation in the cyanide leaching circuit proposed is a SART process Sulphidiation, Acidification, Recycling and Thickening, which is being used presently at many gold plants to recover.

How Is Sodium Cyanide Consumed During Gold Cyanidation

How Is Sodium Cyanide Consumed During Gold Cyanidation

Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires 0.5 grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50-100 times higher than the theoretical calculation.
