The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.

The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to …

The smelting process involves heating and melting ore to extract metal. Refining refers to any process increasing the grade or purity of the metal. The result of the refining process for copper production is copper cathode, which is generally 99.9 percent pure.
