Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products.. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and there is no critical temperature at which this crystal structure changes.

Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This ...
