A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

Recycled aluminum refers t an aluminum that has been processed and reused after it has fulfilled its original purpose. Aluminum is highly recyclable and can be recycled indefinitely without losing quality or properties.Alumina smelting, mining, and ore processing are not needed since recycled aluminum is used, and these processes have already been done in creating the initial aluminum.
