The process used to treat sulfide copper ores begins at the mine site, where the copper bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing

Themon techniques in the United States use cyanide in various ways. 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.
Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
To extract the gold the ore the rock is broken up and carried out of the mine. Then the rock is crushed into a fine dust. Once in dust form the gold is extracted from the rock. Historically this has beenplished using mercury, or on larger scale operations using cyanide. Eventually the gold is extracted frompounds.
