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 of the bauxite greatly increases, which

For industrial purposes, calcined bauxite is used as an abrasive. Sintered bauxite (Calcined bauxite) after crushing and heating at a very high temperature is used for making fine sand-blasting abrasive beads in equipment where friction must be developed to smoothen a rough surface or roughen a smooth surface.

Aluminum oxide sandpaper, polishing powders, and polishing suspensions are made from calcined alumina. Sintered bauxite is often used as a sand-blasting abrasive. It is produced by crushing bauxite to a powder and then fusing it into spherical beads at a very high temperature. These beads are very hard and very durable.

The mineral compositions of calcined bauxite aggregate are mullite and corundum. SiO 2 is mainly found in mullite, and the Moh’s hardness of mullite only is 6. While, the Moh’s hardness of corundum is 9. Calcined bauxite aggregates with the higher contents of Al 2 O 3 show better polish resistance, namely higher PSV value.
