How to Get Aluminum from Bauxite| Reduction Process

2021-10-28  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.

2008-4-1  Three crushing plants are used to reduce the size of bauxite for use in alumina factory. The ore is hauled to these crushing plants by truck from the mine. In the first step the ore is moved to a primary screen with two levels and are divided into three parts: (i) <20 mm (ii) between 20 mm and 10 cm and (iii) >10 cm.
