Aug 19, 2014 At present, the beneficiation of low-grade ores has not been given much importance except in some sources for the removal of silica by size reduction through manual or mechanized breaking. The literature contains a number of references [47] to minimize the reactive silica and iron content particularly from boehmitic or diasporic bauxite ore. However, there is no beneficiation process available that will be used for the removal of impurities from Indian

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
