Pyrometallurgical processes are methods used to extract metals from their ores through high-temperature chemical reactions. These processes typically involve heating the ore in a furnace, where it undergoes melting and reduction to separate the metal from impurities. Common techniques include smelting, where metal is extracted from its ore, and roasting, which involves heating the ore in the presence of oxygen to remove volatile substances. These processes are essential in the production of various metals, including copper, zinc, and iron. The high temperatures required can be achieved using fossil fuels or electricity, making pyrometallurgy a crucial part of the metallurgical industry.
