Bayer process steps for alumina production As the bauxite is found near the surface, it needs an open-pit mining. Step 1- Crushing process. The first step of the Bayer process is to use the crushing equipment to crush the bauxite ore into particles with a diameter of about 30 mm. As the particle size becomes smaller, the specific surface area

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 aluminum-bearing minerals from the bauxite. Bauxite residue is then separated from the sodium aluminate, allowing alumina to be crystallized from the remaining solution.
