Aug 12, 2022The main component of bauxite is Al 2 O 3, containing a small amount of Fe 2 O 3, SiO 2, and other impurities. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, and also to increase the alumina content. In addition, bauxite beneficiation can also be used for iron extraction or iron removal.

Beneficiation Bauxite-India has initiated research into the possibility of beneficiation for the Amarkantak Range Premium bauxite ore. Beneficiation has two main advantages: Ore grade quality is improved by removing non-ore materials. Improved levels of extractable alumina reduces quantity of ore transported and therefore decreases freight costs.
