metallurgical process of copper

Extractive Metallurgy of Copper ScienceDirect

This copper is recovered by simple melting of high purity scrap and smelting or refining of impure scrap. About 80% of the world's copper from ore is produced by concentration, smelting, or refining of sulfide ores. The other 20% is produced by heap leaching, solvent extraction, or electrowinning of oxide and chalcocite ores.

Pyrometallurgical Process - an overview ScienceDirect

The next step is the converting process in the Cu converter by blowing hot air from tuyeres in order to obtain molten Cu matte (Cu–Fe–S) (35%–70% Cu). This step oxidizes iron sulfide and converts copper sulfide to metallic blister Cu (about 98.5% Cu). The last step is anodic Cu production in a furnace (99.5% Cu).
