Product Description
Calcined bauxite is one of the main ores of aluminum. Calcined bauxite contains hydrated alumina and aluminum hydroxide and is formed by the lateritization of aluminum rocks
In tropical and subtropical regions. Calcined bauxite is obtained by calcining (heating) high-quality bauxite at high temperatures (85°C to 1600°C), which removes moisture and increases the alumina content. Calcined bauxite ore has an alumina content of 75% to 90%, compared to approximately 57% to 58% alumina content in primary bauxite ore.
