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 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. So what are the main aspects of cyanide consumption in the
