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.

Insoluble components of the bauxite are removed by digesting the ore with very hot caustic soda (sodium hydroxide) in the Bayer process. A waste by product of the Bayer process for producing al oxide from the bauxite ore, red mud contains toxic heavy metals and its high alkalinity makes it extremely corrosive and damaging to soil and life forms, presenting a massive problem for disposal.

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.

In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in caustic, making it possible for them to be leached, or “digested,” at atmospheric pressure.
