pH/ORP measurement Cyanide leaching process

The carbon captures the dissolved precious metal in solution through a mass transfer process known as adsorption. The carbon moves countercurrent to the pulp flow so that the new carbon contacts with the lowest concentration of goldbearing solution in the final CIP tank. The plant removes the loaded carbon at the first CIP tank
