12.3 Primary Copper Smelting

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

From copper and nickel processing. Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy. In ...

Copper Concentrate Enrichment Process - 911metallurgist.com

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps. Some ores have associated problems such as chalcocite-coated pyrite and are difficult ...

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 mined is concentrated. The milling of copper ores as practiced in the larger ...

The Role of Pug Mills in Processing Copper Concentrates

The smelting process has been the primary means of copper production for generations. The use of a pug mill to mix and condition copper concentrates prior to smelting helps to improve overall efficiency through uniform processing and a reduction in dust, making it an invaluable tool in the copper processing industry.
