202475 · 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 ...
