beneficiation of bauxite ore iron ore beneficiation

Aug 19, 2014 The literature contains a number of references [4–7] 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 bauxites in general.
