Other major steps in the process are the precipitation of aluminum hydroxide from the sodium aluminate liquor and the calcination of the aluminum hydroxide to produce aluminum oxide (alumina). In this study the minus 1.5″ bauxite ore is ground to minus 3/16″ in a Steel Head Rod Mill operating in open circuit.

Crushed aluminum is made from the ore and used to make aluminum, which is then used to form blocks of aluminum. Crushed Aluminum ore has an average purity of about 95%, compared to 95% in the raw ore. This means that it has a much higher energy content, and thus higher refining efficiency. Crushing aluminum has many benefits for refining aluminum.

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 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.
