The primary production of sulfide concentrates includes smelting to copper matte or blister copper, conversion of matte to blister copper, and refining to copper. Smelting, converting, and fire-refining can use a limited amount of secondary materials. Molten copper can effectively dissolve many metals, from valuable noble metals to harmful impurities such as bismuth.

World Copper Production at a Glance

Once mined, copper ore goes through a series of processing stages in order to refine it into a saleable copper product. Copper can be refined by one of two approaches: pyrometallurgy or hydrometallurgy. Pyrometallurgical Copper Refining. The pyrometallurgical approach, often referred to as smelting, is the primary method used for refining copper.

Copper, Lead and Zinc Smelting and Refining

Copper conversion from the ore to metal is accomplished by smelting. During smelting the concentrates are dried and fed into one of several different types of furnaces. There the sulphide minerals are partially oxidized and melted to yield a layer of matte, a mixed copper-iron sulphide and slag, an upper layer of waste.
