The blister copper is processed further in the anode furnaces to turn out refined copper ready to be mold into copper strips by the machine of Hazelett Twin Belt Caster. Blister copper (copper in the range of 99% purity) was produced by blasting air through the molten copper to remove impurities and drive off most of the sulfur as sulfur dioxide.

Blister copper is processed in an anode refining furnace to remove most of the dissolved oxygen and sulphur. Converting produces blister copper named for the blisters of air/oxygen trapped in the molten material. Approximately 4 unit weights of concentrate are required to produce 1 unit weight of blister copper.
Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting,

Blister copper is refined by electrolysis. Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathodes. The cathode plates are coated with graphite in order to remove depositing copper. The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity.
