Bauxite Processing Beneficiation

Beneficiation of bauxite

The silica present in the bauxite tends to be concen- trated in the finer grained fractions, and this charac- teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.

Beneficiation and mineral processing of bauxite and ...

Beneficiation and mineral processing of bauxite and feldspar Bauxite is a sedimentary rock that is rich in alumina, the base for making aluminum. It is generally easy to mine because it is found near the surface of terrain. However, the process for separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
