Approximately 20% of current world copper cathode output is produced using a hydrometallurgical process route, generally referred to as the leach-solvent extraction-electrowinning flowsheet.
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. …

The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage).

Other processes, such as matte leaching used at Port Pirie, operate with a PLS of
This study shows the feasibility of recovering copper directly from Pregnant Leaching Solutions (PLS), using the reactive electrodialysis technique, without the need of solvent extraction.
The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to …

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
