Deposits of bauxite ores near aluminum smelters often possess an excessively high percentage of silica. Development of such high-silica ores would be beneficial to alumina producers. Therefore, unique industrial and operational experience in the field of high-silica bauxite processing was gained at the Russian National Aluminium-Magnesium Institute, St. Petersburg, pilot plant with the

The removal of 85% of iron was also remarkable. It has to be noted that when leaching bauxite by means of organic acids, reprecipitation of silica from the solution takes place because of its low equilibrium solubility. An alkaline wash of the solid residues after leaching is required in order to redissolve the precipitated silica.

2018-11-01· Our results found that Arthrobacter pascens H19 and Burkholderia anthina G21 could significantly (p < 0.05) remove Si from the high silica bauxite (Fig. 1, Table 1, Table 2). In the presence of strains H19 and G21, the ratio of Al 2 O 3 /SiO 2 in the residual bauxite was more than nine, suggesting that after bio-desilication by both strains, the bauxite was suitable for the Bayer process

The work to be carried out involves the partial removal of silica from bauxite ores by means of microorganism assisted leaching. The bauxite ores to be studied are those of interest to the industrial partners and include high silica bauxite from Greek deposits (Parnassus - Ghiona area) and high silica bauxite from Italian deposits (Nurra area, Sardinia). The work programme will be implemented

Bauxite ore was carefully prepared, by comminution operations and size separations, specifically to minimise fines generation. After that stage the ore was deslimed. The final size range of the bauxite sample was: -150 µm + 15 µm. The preparation of bauxite caused an increase in the alumina/silica mass ratio from 7.30 to 11.05.
