The process of producing oxygen-free copper begins with separating the copper mineral from the ore by crushing the ore into a fine powder and then melting it in a furnace. Impurities are extracted either by oxidizing to vapor or adding fluxes to form slag, which is later removed.

Copper Ore Processing Methods. 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

Copper crushing process machines. Crushing – Primary. Primary crushing was done by a jaw-crusher – like a giant nutcracker. This consisted of two jaws, one static, and one moving. Ore would move between the jaws and was crushed if it was larger than the gap between the jaws. The jaws did not close completely but were set 4 or 6 inches apart.
