Extraction of Aluminium From Bauxite, Bayer's & Hall's Process

Hall-Heroult Process. The Hall–Héroult process is a major industrial process that involves the smelting of aluminium. It involves dissolving aluminium oxide (alumina) obtained from bauxite through Baeyer's process. In this process, pure alumina is mixed with Calcium fluoride ( C a F 2) or Cryolite ( N a 3 A l F 6).

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.
