copper smelting process

Copper Smelting an overview ScienceDirect Topics

Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.
