Fire refining and electrolytic refining are used to purify blister copper even further. In fire refining, blister copper is usually mixed with flux and charged into the furnace, which is maintained at 1100 C 2010 F. Air is blown through the molten mixture to oxidize the copper and any remaining impurities. The impurities are removed as slag.Fire refining and electrolytic refining are used to purify blister copper even further.
