Bayer Process - an overview ScienceDirect Topics

In the Bayer process (Fig. 2), bauxite received from the mines is crushed to a particle size of less than 25 mm, usually by a hammer mill, blended to obtain a more uniform feed for the process, and stored. From storage the bauxite is metered into wet grinding-rod mills, where spent liquor (recycled NaOH solution) is used as a grinding medium. Lime (CaO) or sometimes do-lime (CaO

Bayer process, comprising grinding (L, B) and then digestion (N 2, A) of a bauxite by bringing it into contact with a sodium aluminate liquor ( 20 b, 120 b ). Digestion consists of forming a slurry ( 3 a, 103 ) that is then treated to separate insoluble residues ( 5 a, 105 a ) from the sodium aluminate liquor.

Mining and Refining – Process - World Aluminium

The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production. The process stages are: 1. Milling. The bauxite is washed and crushed, reducing the particle size and increasing the ...

Pyrometallurgy Process Of Bauxite Ore - MC World

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 In this process bauxite ore is the main raw material and it is digested together with lime addition by a solution of caustic soda (NaOH). This causes a saturated solution of sodium
