ores to expose the gold particles before cyanidation. Thioura leaching was developed as a potential substitute to cyanide leaching due to its lower toxicity and greater rate of gold and silver dissolution. Other alternative lixiviants to cyanide such as bromides (acid and alkaline), chlorides and thiosulfate are also being developed.

CLS will leach pieces of gold 40 mesh and smaller within 8 to 12 hours. This is a definite advantage over cyanide which can take up to a week to leach 40 mesh gold. This presents a number of trade-offs between CLS and cyanide. In most cases, the CLS leaching system can .
