    The same holds true for those minerals, such as bauxite or excess silicate containing minerals, in which either the excess iron present is directly reduced anaerobically by using iron reducing bacteria to biobeneficiate bauxite ore or clay, or extra silicate is directly removed from low grade ores using silicate degraders (biobeneficiation).

    Biobeneficiation of bauxite using Bacillus polymyxa

    Calcium and iron removal from a bauxite ore by Bacillus polymyxa has been demonstrated. Within a period of 7 days, the above organism could remove all the calcium and about 45% of iron from the ore in the presence of 2% sucrose in a Bromfield medium. The highest removal of calcium and iron corresponded with the maximum in extracellular polysaccharide production by the organism.
