Day 54, Gold extraction by cyanidation Rio Suerte
Day 54, Gold extraction by cyanidation. Dissolution. Gold found in ores in small amounts less than 10 g / t, or 0.001%. Sulphide bearing ores, or carbonates, require additional treatment before the gold leach process, because cyanide tends to leach mineral sulfides instead of gold, and carbonates to join the gold dissolved.
