Blister Copper - an overview | ScienceDirect Topics

Fire refining is usually carried out prior to the electrolysis of copper. The fire refining is operated in either reverberatory or rotary furnaces known as anode furnaces. Through this step, oxygen and other impurities in the blister copper can be removed before the copper is cast into anode for electrolytic refining.
