The cyclone overflow is pumped to a 64 meter diameter concentrate thickener, while the underflow containing the coarse material, is screened on two 0.7 …
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.

The latter operation produces finished copper concentrate, finished pyrite concentrate, and middlings which are re-treated.". The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.
For making copper wire, electrolytic copper may be cast into wirebars, which are made in several standard sizes varying in weight from 60 to 225 kg (135 to 500 pounds). The wirebars are then reheated to 700 to 850 °C (1,290 to 1,560 °F) and are rolled without further reheating to rods approximately 10 mm (0.375 inch) in diameter.
