Copper Electrorefining Last step Elmhurst College

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.

Recovering Scrap Anode Copper Using Reactive Electrodialysis

In overall, despite functioning without major operational problems, the copper electrorefining process in actuality does not allow complete use of copper anodes, only peaking at 85% of the copper anode in weight. Consequently, the remaining 15% of scrap copper must be recirculated into the copper smelting.

The Electrorefining of Copper from a Cuprous Ion

A preliminary capital cost estimate made for the copper(/) I chloride system showed that, for it to be cost competitive (that is, a reduction of capital cost of about 15-20%) with the conventional electrorefining process, the refining cells would have to be operated at a current density of about 25-30 mAl cm 2.

More noble metals with a higher reduction potential are not dissolved at the anode, instead they collect at the bottom of the cell as anode slimes. The anode slimes can be captured and processed to recover the valuable metals. Cell voltage and current density are the two important parameters in copper electrorefining.
