The beneficiation of an Indian bauxite ore can be done by removing iron through magnetic separation (Mohapatra et al., 2000). Beneficiation of the product having 92.6% Al 2 O 3 and 2% Fe 2 O 3 can also improve the overall recovery of the ore. This beneficiated product as starting material would be highly beneficial in the Bayer's …
