Sepro Leach is a chemical additive used to increase the rate of gold leaching within cyanide systems. Sepro Leach is typically used for intensive cyanide leaching of gravity concentrates but can also be used to improve leach kinetics in conventional cyanide leaching systems. Additionally, laboratory testing can be used for rapid determination of cyanide extractable gold.
