bauxite ore dressing process

How to Get Aluminum from Bauxite| Reduction 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. Step 2- Washing and separating processes
