Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill

Copper minerals generally occur as oxides or sulfides. These require different treatments for extraction of the metal. The oxides are exposed to acid in a heap leach; this liberates the copper ions and the resulting solution is then sent to the solvent extraction (SX) process followed by electrowinning (EW) of the copper.
