Copper Refining: From Ore to Market INN

The blister copper is recovered and is then subjected to another process called fire refining. In fire refining, air and natural gas are blown through the copper to remove any remaining sulfur and oxygen, leaving refined copper behind to be processed into copper cathode. This copper is cast into copper anodes and placed in an electrolytic cell.
