Gold Processing In Cyanide

How is Sodium Cyanide Consumed during Gold .

Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50100 times higher than the theoretical calculation.
