  • 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 05 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.
