Extractive Metallurgy of Copper | ScienceDirect

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