The process design of gold leaching and carboninpulp circuits
Before leaching the pH of the pulp is normally adjusted to a value of around 95–11 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 used in the industry, mechanically agitated reactors are preferred due2015年11月1日· CIL circuit is a process of continuous leaching of gold from ore to liquid and countercurrent adsorption of gold from liquid to carbon particles in a series of tanks The CIL process concentrates gold from 25–35 g/t in ore to 2000 to 6000 g/t on carbonModeling and optimization of Carbon in leach (CIL) circuit for gold
