  • The process design of gold leaching and carboninpulp ...

    Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around –11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly ...
