Pyrometallurgy is a branch of extractive metallurgy that involves high-temperature processes to extract and purify metals from ores or other raw materials. The term "pyro" refers to heat, indicating that heat is a key component of the processes involved. In pyrometallurgical processes, various techniques such as smelting, roasting, and refining are employed to separate desired metals from their ores or concentrates by utilizing heat to drive chemical reactions and physical transformations. This contrasts with hydrometallurgy, which uses aqueous solutions for metal extraction processes. Pyrometallurgy is commonly used in the production of metals like iron, copper, lead, zinc, and nickel. read less
