The process design of gold leaching and carbon in pulp

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 9 5–11 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
