2021-4-22 Bauxite is the main ore of aluminium with silica (SiO 2), ferric oxide (Fe 2 O 3) and titanium oxide (TiO 2) as impurities in it. In this process, the bauxite ore is first crushed and then it is leached by heating with hot concentrated caustic soda (NaOH) solution under high pressure for 2 to 8 hrs at 140 to 150 °C in a tank called a digester.

Leaching of Alumina from bauxite. Leaching of alumina is done by the Bayer's process. The principal ore of aluminium, bauxite, usually contains SiO 2, iron oxides and titanium oxide (TiO 2) as impurities. Concentration is carried out by digesting the powdered ore with a concentrated solution of NaOH at 473 – 523 K and 35 – 36 bar pressure.

2015-4-21 In this paper, the effects of temperature, oxidation time, and oxygen concentration on the conversion of sulfur by wet oxidation in the Bayer process were investigated at length. The results show that active sulfur S2− and S2O3 2− in sodium aluminate solution can be converted completely by wet oxidation during the digestion process, thus the effects of S2− and S2O3 2− on alumina ...

Bauxite is concentrated by: Chemistry Questions
The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The N a O H will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.This method is called the chemical method.

When is Serpeck's process preferred over Bayer's process?
2015-5-5 Serpeck's process, on the other hand, is used to leach White Bauxite, which has Silica as main impurity. Both are efficient for their respective ores. But Baeyer's process is more frequently used, as Bauxite, more often than not, is also a source of Gallium, which can be extracted from Baeyer's process.
