Copper Mining and Production Processes Explained

Electrolytic refining. The copper is purified to 99.99% by electrolysis. The production route described above shows the progression from a rock containing about 0.2% copper to a copper cathode of 99.99% purity. Leaching. Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid.

Definitions - International Copper Study Group

Refined copper is obtained by electrolytic refining, electrolytic extraction, chemical refining or fire refining. Other refined copper (containing at least 97.5 % by weight of copper) is normally produced by alloying refined copper with one or more other elements up to the maximum content limits as shown in the foregoing table.

Metallurgy - Refining | Britannica

The procedure is accomplished in three ways: refining by fire, by electrolytic, or by chemical methods. Iron, copper, and lead are fire-refined by selective oxidation. In this process, oxygen or air is added to the impure liquid metal; the impurities oxidize before the metal and are removed as an oxide slag or a volatile oxide gas.

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

Electrolytic Refining - Meaning, Electrorefining of Copper ...

Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode. In this setup, an electrolyte (metal salt aqueous solution) depending on the metal is often used.
