The extraction of Aluminium from natural deposits of bauxite requires complex and expensive processes. In the ‘Bayer process, the bauxite is first mixed with sodium hydroxide, autoclaved and then stirred. After that, it is fed into the calciner (high temperature kiln), where it dehydrates to a fine white powder, aluminium oxide (Al2O3). Level measurement in this tank ensures optimal operation of the process.
