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. Consequently, it is ductile and possesses a high level of electrical and thermal conductivity, making it attractive for a wide range of ornamental and practical applications. With cold-working, copper becomes harder, but it can be made soft ...(100 of 4534 words)
