The Transformation of Bauxite to Aluminum (and the ...

The Bayer process is not easily explained in brief. This method of obtaining alumina from bauxite ore is complex and involves a lengthy succession of chemical reactions, with the process varying slightly depending on the makeup of the unique source of bauxite ore. Crushed and washed bauxite ore must first go through a process to remove any ...

Bayer process [SubsTech]

Dr. Dmitri Kopeliovich Bayer process is the process of refining alumina from bauxite (aluminum ore containing 30-50% of hydrated aluminum oxide) by selective extraction of pure aluminum oxide dissolved in sodium hydroxide. Prior to the Bayer process bauxite is crushed and ground in mills to fine particles (max. size 0.06"/1.5mm).

SUSTAINABILITY IN ALUMINA PRODUCTION FROM BAUXITE

BAYER PROCESS Alumina is mainly produced from bauxite ore through the well-known Bayer process, a hydrometallurgical process invented by Carl Josef Bayer in 1888-1892. 1 A simplified process flowsheet for the process is illustrated in Figure 2. In this process bauxite ore is digested with lime addition by a solution of caustic soda (NaOH).
