Beneficiation of bauxite - eprints@NML

2011-8-11  out the ore, and it is often necessary to beneficiate the bauxite to provide a desired quality of product. A primary objective of the beneficiation process is to reduce the silica content in the ore, as the latter reacts with caustic soda during the digestion step to precipitate out as insoluble sodium aluminium silicates, e.g. 2Na2O.2Al20;,.3Si02.2 H20.

Beneficiation of diasporic-bauxite ore by selective ...

2008-8-1  The beneficiation of mixtures and diasporic-bauxite ore by selective flocculation can be done with Na 2 CO 3 and PAS at pH about 9–10, but it is sensitive to the content of kaolinite. For the beneficiation of diasporic-bauxite ore, a concentrate can be obtained with the Al 2 O 3 recovery of 87.0% and Al 2 O 3 /SiO 2 ratio of 8.9.

Grinding Behavior and Potential Beneficiation Options of ...

This laboratory study investigates selective grinding and beneficiation options for a Greek bauxite ore. First, a series of batch grinding tests were carried out in order to investigate the grinding behavior of the ore and the effect of the material filling volume (f c) on the distribution of aluminium- and iron-containing phases. Then, the ground ore was subjected to magnetic separation either as received or after reduction roasting in order to further explore potential beneficiation
