STEP 1 - Crushing and Grinding: Alumina recovery begins by passing the bauxite through screens to sort it by size. It is then crushed to produce relatively uniformly sized material. This materials is fed into a large grinding mill where it is mixed with a caustic soda solution (sodium hydroxide) under high temperature and pressure.

Crushing & Grinding. The purpose of crushing and grinding is to reduce the size of the potential ore particles to that where there is sufficient REE mineral liberation and the size/size distribution is suitable for the chosen downstream mineral recovery process. This allows for the subsequent REE mineral recovery processes to function in an ...

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 helps to speed up the follow-up speed of the chemical reaction.
