Exporting finished copper - Mining For Zambia
Copper goes through many similar phases of beneficiation. It is converted from ore to copper concentrate, and then into copper anode, and then into copper cathode, which is 99.99% pure. Cathode copper is then processed further into tubes, sheets, wiring and other forms.

copper processing | Definition, History, & Facts | Britannica
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.

Copper slag is a byproduct of the copper smelting industry. Generally, 2.0–3.0 tons of copper slag is generated per ton of copper produced in the whole process, depending on the properties of the copper sulfide concentrates and the operating conditions.1,2 It is estimated that approximately 12 million tons of copper slag is discharged into the environment annually in China.
Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
