Extraction of Copper: Detailed Process

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.
