Calcined Bauxite is produced by heating high-grade bauxite at high temperatures, typically between 850°C and 1700°C. This process removes moisture and increases the alumina content, improving its refractory properties.
While raw bauxite contains around 57–58% alumina, calcined bauxite offers a higher alumina content of approximately 82–86%. Calcination is carried out in rotary kilns, with temperatures adjusted based on the required application.
Calcined bauxite is widely used as a key raw material in the refractory industry. It is also used in abrasives, steel processing, slag conditioning, refractory alumina Calcined cement, road construction, mineral wool production, and welding applications.
