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.

The copper obtained after the fire refining process still contains a significant amount of impurities (0.2– 1.1%) in its composition; therefore, it undergoes electrolytic refining aimed at ensuring high-purity copper (99.9% Cu) and extracting precious metals and other valuable impurities (selenium and tellurium) from it [4, 5].

In 1975, the total input of copper into China's anthroposphere was 381.2 Gg, with 64% coming from the domestic extraction and 36% coming from imports. While in 2010, the total input increased to 6012.8 Gg, with the proportion between domestic extraction and imports being 0.26:0.74.
