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.

Mining Method – Resolution Copper
The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells. When mixed with water, reagents, and air, the copper minerals produce a bubbly froth. The bubbles with copper are skimmed and filtered to produce copper concentrate. The concentrate, which contains about 29-31% ...
