In the bauxite grinding plant, aluminum ore begins with crushing and grinding to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite.Often,the bauxite ultrafine mill will play an important role in the bauxite processing.

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.

used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers ( m) or smaller by grinding, using smooth rolls, media mills, autogenous mills, hammer mills, or jet mills. The ground material then is classified by wet screening, dry screening, or air classification.

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.
