Copper Production: How Is Copper Made? The Balance

The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80 percent of global copper production is extracted from sulfide sources. Regardless of the ore type, mined copper ore must first be concentrated to remove gangue, unwanted materials embedded in the ore.

Copper Mining and Extraction: Sulfide Ores

Copper Mining and Extraction: Sulfide Ores. Copper has a remarkable combination of properties. It is a good electrical and thermal conductor. It is ductile and it can prevent bacterial growth (see Copper: Properties and Applications ). As with all world resources, the supply of copper from the ground is limited.

MANAGERIAL REVIEW Examining the copper value chain

The first step in the value is mining the ore. As the copper content of the ore has only % copper, it is enriched by flotation to a copper concentrate with about 2535 % copper to avoid processing of a high amount of gangue material. So copper concentrate is the first traded product with a value.

World Copper Production at a Glance

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 ...

copper extraction and purification

Purification of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper hence "blister copper") and then cast into anodes for refining using electrolysis.
