  • Biox174 Process Outotec

    Biox174 Process Outotec

    As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite the gold is prevented from being leached by cyanide the biox process destroys sulfide minerals and exposes the gold for subsequent cyanidation thereby increasing the achievable gold recovery improves rates of gold recovery reduces capital cost
