How Is Gold Extracted From Gold Ore? | Sciencing
In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. 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 carboninpulp method, the ground ore is mixed with water before cyanide is added.
