Electrometallurgy is a branch of metallurgy that uses electrical energy to extract and refine metals from their ores. This process often involves electrolysis, where an electric current is passed through a solution containing metal ions, causing the metal to deposit onto an electrode. Commonly used for metals like aluminum and copper, electrometallurgy is essential for producing high-purity metals. In addition to extraction, electrometallurgy can also be used for metal plating and surface treatment. Techniques such as electroforming and electropolishing enhance the properties of metals, improving their durability and appearance. This field plays a crucial role in various industries, including electronics and aerospace.
