Pyrolusite is a manganese oxide mineral, composed primarily of manganese dioxide. It is one of the primary ores of manganese, an essential element used in the production of steel and other metal alloys. Pyrolusite typically occurs as prismatic crystals, fibrous aggregates, or compact masses. Its color ranges from steel gray to black, and it has a metallic to submetallic luster. Pyrolusite is known for its tetragonal crystal structure. Its ability to catalyze the decomposition of water into oxygen and hydrogen has important industrial applications. It plays a crucial role in ore processing and battery production. Manganese extracted from pyrolusite is also used to improve the hardness and corrosion resistance of steel. Pyrolusite is often found in association with other manganese minerals such as rhodochrosite and manganite. Its formation is usually the result of the oxidation of these minerals under specific geological conditions. The main deposits of pyrolusite are found in South Africa, Brazil, India, and China.
