What Is the Bayer Process?

The first process of the Bayer process is to use a pulverizer to crush the bauxite ore into particles with a diameter of about 30 mm, and then rinse the surface of the particles with water. The Bayer process has been used in the production of alumina for more than 100 years, and has been greatly developed and improved for decades, but it still ...

Bayer process - Wikipedia

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. The aluminium oxide must be purified before it can be refined to ...

Bauxite ore processing Plant

Bayer process is the main industrial method in alumina producing. Bayer process is suitable for processing low silicon bauxite with good quality but is not suitable for goethite with aluminum. The production process is that: in the pressure cooking device, caustic alkali is used to leach bauxite so that we can get sodium aluminate solution.

bauxite crushing processing

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.
