2011-8-11 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%. The beneficiation step also leads to an enrichment of the alumina content in bauxite as the finer fractions contain low alumina.

In the Bayer plant, bauxite mineralogy affects process efficiency by driving the chemical reactions that occur in the process. If the Run Of Mine (ROM) bauxite is of lower quality, in some cases the beneficiation by means of physical separation process is economical feasible. These generally low-cost processes can extend the lifetimes of existing bauxite mines considerably, and substantially improve the technical and economic basis of the Bayer process

2009-8-1 The Bayer process is the principal method for the production of alumina from bauxite worldwide. The modern version of the process (developed in the 1880's) still maintains the key steps of dissolution of alumina-rich minerals into hot caustic solution, separation of the insoluble phases, followed by gibbsite precipitation and calcination of the gibbsite to alumina (Al 2 O 3).

Abstract. Many bauxite reserves in India have Al 2 O 3 /SiO 2 ratio of 4 to 6 and hence pose difficulties in production of alumina through the Bayer process. The extraction of alumina from bauxite in low temperature digestion circuit frequently involves a desilication step in which kaolinite dissolves and reprecipitates as sodalite, a caustic insoluble sodium alumino silicate.

Mining and Refining – Process - World Aluminium
Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.
