Bayer Process | Extraction of Aluminium | Extractive Metallurgy

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 ...
