treatment of copper ores

How is Copper Made? | What Is Copper Made of? - Worldcoppersmith

To remove or reduce the levels of impurities the blister copper is fire refined before being sent for final electro-refining. Heated in a furnace similar to a converter, the blister copper has air circulated through it to oxidize some of the impurities. In some cases, a sodium carbonate flux is to remove arsenic and antimony traces.

copper extraction and purification - chemguide

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. Electrolytic refining
