Copper, Lead and Zinc Smelting and Refining

Copper ore typically contains less that 1% copper in the form of sulphide minerals. Once the ore is delivered above the ground, it is crushed and ground to a powdery fineness and then concentrated for further processing.

World Copper Production at a Glance - FEECO International Inc.

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. In this process, used for sulphide ores, copper concentrates are thermally treated in a smelter and then refined into a pure copper product.

USGS Minerals Information: Copper

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.
