bauxite, but not exactly about the PLK rocks. Bhatacharya and Mookherjee (Bhatacharya and Mookherjee, 1987) discussed about the beneficiation of bauxite. They also discussed about the different grades of bauxite of India. Refractory grade bauxite contain Al2O3% > 56-58%, SiO2% - 5% and Fe2O3% - 3%. Scheider et
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.

Many bauxite reserves in India have Al2O3/SiO 2 ratio of 4 to 6 and hence pose difficulties in production of alumina through the Bayer process.
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.

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.
the process. 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%.
Bauxite deposits invariably contain a range of impurities, ranging from organic material to trace elements such as Ga, Zn, Pb, P and Be. Table 2.1 shows typical compositions of a range of smelter aluminas. In the Bayer process, many impurities are at least partially soluble in the caustic digestion liquor and may be carried over into precipitation if they are not removed in the desilication ...
