Electrorefining of Copper

Fire-refined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage

metallurgy

The procedure is accomplished in three ways: refining by fire, by electrolytic, or by chemical methods. Fire refining. 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.

BACKGROUND REPORT SECONDARY COPPER SMELTING, …

Leaching is used to recover copper from slime, a byproduct of electrolytic refining. In this process, sulfuric acid is circulated through the slime in a pressure filter. Copper dissolves in the acid to form a solution of copper sulfate (CuSO 4), which can then be either mixed with the

 · The refining anodes taken out from the refining furnace is changed into electrolytic copper with purity of 99.99% through an electrolysis process: During electrolysis, copper (II) ions leave the impure copper anode and since they are positive, migrating to the negative cathode. From time to time, the pure copper is scraped off the cathode.

Refining (metallurgy)

Electrolytic refining. The purest copper is obtained by an electrolytic process, undertaken using a slab of impure copper as the anode and a thin sheet of pure copper as the cathode. The electrolyte is an acidic solution of copper sulphate. By passing electricity through the cell, copper is dissolved from the anode and deposited on the cathode.
