Copper Production: How Is Copper Made? - ThoughtCo

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
