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.

Indian Amarkantak Bauxite Ore is suitable for refining due to the following. Available alumina to reactive silica ratios. Comparatively lower energy in the refining process compared to other bauxite ore. Located in a politically secure and mature business location. Relatively close to the emerging markets of Australia and China.

Bauxite Beneficiation: Social Benefits: ... As India bauxite contains more gibbsite, it is more suitable to this process.
