The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9. The sinter process is widely used to process the poor-grade diasporic bauxite ores with A/S below 7, in China and Russia, by sintering the bauxite ore with sodium carbonate and limestone to form sodium aluminate and calcium silicate.
The Bayer process is a chemical process widely used in the industry to produce alumina from bauxite. Invented by Austrian engineer Karl Joseph Bayer in 1887, the basic principle is to convert aluminum hydroxide to sodium aluminate with concentrated sodium hydroxide solution, and to re-precipitate aluminum hydroxide by diluting and adding aluminum hydroxide seeds.

Sep 14, 2021 Bayer Process Overview. The Bayer process is a typically divided into two areas referred to as the red and white sides. In the red side, feed bauxite is crushed and mixed with a sodium hydroxide (NaOH) leachate, known as caustic soda or Bayer liquor. The slurry mixture is heated to 150-250C in autoclave or tube digestion where aluminium-bearing species (e.g. gibbsite, boehmite and
Employing the Bayer process, synthesis of nano alumina has been made from natural bauxite followed by sol-gel route. The ultra fine alumina powder with high surface area is obtained through the digestion of gel followed by sintering. The size of the particle and its morphology was controlled by calcination temperature and processing time.

Gallium is normally obtained by direct electrolysis as a by-product from Bayer process residual liquor at an aluminum processing plant. However, to permit any net accumulation of the metal, the gallium concentration must be at least about 0.3 g/l in the liquor. This article describes a continuous process of extraction with organic solvents and rhodamine-B, followed by a re-extraction step into ...
