The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press. For the carbon in pulp method, the ground ore is mixed with water before cyanide is added. Then carbon is added to bond with the gold. The carbon gold particles are put into a caustic carbon solution, separating out the gold. In heap leaching, the ore is
When these materials harden the gold can be easily separated from the slag. The slag frequently contains addition gold that can be recovered through reprocessing. Chemical Leaching. Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining
