• Thiourea leaching • This method was developed as a potential substitute for cyanidation (of gold as well as silver). Thiourea's lower toxicity and greater rate of gold and silver dissolution compared to cyanide give it an advantage inreaching commercial application before other non-commercial lixiviants [2].
