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 …
