Beneficiation
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 Mineral Processing Employed
The major method of bauxite beneficiation is the Bayer process, which is leaching at 100 °C to 250 °C by a caustic soda solution (sodium hydroxide) followed by solid-liquid separation, cooling, precipitation, filtration and calcination, with alumina as the final product. The process dissolves the majority of the alumina-bearing minerals and …
