Alumina: Processes and Uses

Alumina: Processes and Uses

Alumina is primarily derived from bauxite ore through the Bayer process, in which a caustic soda material, in combination with heat and pressure, is used to dissolve aluminumbearing minerals from the bauxite. Bauxite residue is then separated from the sodium aluminate, allowing alumina to be crystallized from the remaining solution. The crystallized alumina is then thermally processed in a ...
