Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al(OH) 3).It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.

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

Bauxite is a rock type that is used to produce metallurgical-grade alumina and chemical-grade alumina/aluminum hydroxide using the Bayer process [ 8 ]. During this process, the finely ground bauxite ore is digested under pressure in a strong caustic (sodium hydroxide) solution at temperatures ranging from 100 to 260 °C.
