Bayer Process | Stone Crusher
Bayer Process Bayer process is a leaching process of bauxite. This process is use to produce high purity alumina (needed in subsequent electrolysis process) by leaching bauxite by NaOH. Leaching is done in autoclave at high presuure ( 25-30 atm) and high temperature (220 o C), which produces a soluble aluminate (2NaAlO 2), and from which we precipitate out Al (OH) 3. …

Bayer process
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. [1]
