Pyrometallurgical process

Pyrometallurgy is a process of extracting metals from their ores using high temperatures. It involves heating the ore to cause chemical changes—such as melting or oxidation—that separate the desired metal from impurities. The process typically includes steps like roasting, smelting, and refining, often in furnaces. By applying heat, the metal components become liquid or vapor, making it easier to collect and purify them. Pyrometallurgy is commonly used for metals like copper, nickel, and zinc, enabling efficient extraction and refining at industrial scales.
