The 99% pure copper from the anode furnace is cast into 750-pound, 3-inch thick, rectangular slabs called anodes. The final step is a process called electrorefining. This is done by electrolysis where the copper anodes from the smelter become positive electrodes and thin, three-foot square sheets of pure copper are used as negative electrodes.

Get PriceAnswer: Electrorefining is a process used to make impure copper pure. The smelting process takes copper ore and processes it into metal. This metal (sometimes called blister copper contains other metals. These other metals often include gold, silver, arsenic
Get PriceWhere copper has been contaminated and it is required to re-refine it, it is normally remelted and cast to anode shape so that it can be electrolytically refined. If, however, the level of impurities in the cast anode is significant, it is unlikely that the cathode produced will then meet the very high standards required of grade 'A' copper used for the production of fine wires.
