1. Introduction. Copper-making by the pyrometallurgical process is based on extracting elemental copper (Cu°) from a multicomponent system of polymetallic sulphides in four steps: fusion, conversion, fire refining and electrolytic refining [1], [2], [3]:. Fusion of the concentrates is a continuous oxidative process.

Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.

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.
