The process The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal .
Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials.
A buddle pit or buddle pond is a pit, often circular when specifically constructed, the purpose of which was to separate by sedimentation minerals from lighter rock dust in crushed ore, and used in the mineral mining industry (such as in extracting tin, lead and zinc).
