The copper is cast into copper anodes and placed in an electrolytic cell. Once charged, the pure copper collects on the cathode and is removed as 99% pure. The copper can be sold to wire-rod mills or further processed into rods. Anode slime refers to impurities that sink to the bottom of the electrolytic cell.

From the smelter the molten, impure copper ore is ferried over to the refinery in giant soup cups and put through more heat treatment. Eventually it is cast into anodes three feet square and a couple of inches thick. The anodes are hung vertically in acid-filled tanks. Between each one and the next is hung a paper-thin pure copper cathode.
