Extractive Metallurgy is the branch of metallurgy that focuses on the extraction of metals from their ores. This process involves several steps, including crushing and grinding the ore, followed by concentration to separate valuable minerals from waste material. The goal is to obtain a pure metal or metal compound for further use. Once concentrated, the metal is extracted through various methods, such as pyrometallurgy (using heat) or hydrometallurgy (using aqueous solutions). These techniques help to refine the metal and remove impurities, making it suitable for applications in industries like construction, electronics, and manufacturing.
