Mining and Refining – Process - World Aluminium

The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production.

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 ...

num oxide from bauxite. The process has been refined and improved since its inception. Fig. 2.2 shows that the production of alumina is a complex chemical process. The alu-mina content of bauxite ores varies from one deposit to another, and methods of treat-ment differ accordingly (see 16.1.2). This means that each alumina plant is almost tailor-

Production process - EUROPEAN ALUMINIUM

Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the so-called “bauxite residue”, followed by a calcination step which removes the water content in the hydroxide.
