About 80% of the world's primary copper is produced by concentration, smelting, and refining of sulfide ores. The other 20% is produced by heap leaching, solvent extraction, and electrowinning of oxidized and chalcocite ores. Secondary copper production from recycled end-of-use objects is 15%–20% of primary copper production.

Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copper-bearing solution with scrap iron.

Modern smelters are designed to collect at least 90 percent of the sulfur in the feedstock. These steps result in the following reaction: 2 CuFeS2 + 2 SiO2 + 4O2 → Cu2S + 2 FeSiO3 + 3SO2. Copper extracted by this method is combined with slag to create a material known as Matte Copper due to its matte look.
