Purification of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper hence "blister copper") and then cast into anodes for refining using electrolysis.

Intermediate product in the copper refining process, containing about 99% copper. Produced by oxidizing copper matte (mixture of copper and iron sulfides) to remove iron and reduce copper to its elemental form. Sonamed because the process forms bubbles of sulfur dioxide on the surface of the copper. Blister copper must be further refined before use [.]

Poling is a [metallurgical] method employed in the purification of copper which contains copper oxide as an impurity and also in the purification of tin ("Sn") which contains tin oxide (stannic oxide or "SnO2") as an impurity. The impure metal, usually in the form of molten blister copper, is placed in an anode furnace for two stages of refining.
