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.

Bauxite mining can pollute the air, water and soil, thus directly affecting the environment. Air pollution The substances produced during the bauxite mining process include dust, sulfur dioxide (SO2), and nitrogen oxides (NOx). The mining and beneficiation of bauxite do not involve the use of chemical reagents and produces no odors.

The beneficiation of mixtures and diasporic-bauxite ore by selective flocculation can be done with Na 2 CO 3 and PAS at pH about 9–10, but it is sensitive to the content of kaolinite. For the beneficiation of diasporic-bauxite ore, a concentrate can be obtained with the Al 2 O 3 recovery of 87.0% and Al 2 O 3 /SiO 2 ratio of 8.9.

Processing of bauxite for smelter grade alumina is quite sensitive to bauxite recovery and total cost for processing of ore, particularly in wet beneficiation. On the other hand, owing to homogeneous nature and consistent quality, some alumina refineries prefer washed ore compared to simple crushed run-of-mine (ROM) bauxite.

The microstructure of bauxite determines to a significant extent the opportunities for its beneficiation and optimum processing downstream. Adequate fine grinding commensurate with its microstructure may result in proper mineral liberation and grain size distribution required for effective ore dressing (i.e. H/M or magnetic separation) and digestion respectively.
