Industrial grade pyrometallurgy is usually direct put the WPCBs containing 5%–40% copper into the blast furnace, and the product is black copper containing 70%–85% copper. The black copper is then poured into the converter, which makes an oxidizing slag of Pb, Zn, and Sn, and the copper that contains 95% copper content.
