Pyrometallurgy is a branch of metallurgy that involves the extraction and processing of metals from their ores using high-temperature chemical reactions. This method is primarily used to extract metals such as copper, iron, lead, zinc, and various precious metals. The general process of pyrometallurgy typically includes the following steps: 1. **Roasting**: Ores are heated in the presence of air or oxygen to convert sulfides into oxides or to remove volatile impurities.
