Froth Flotation Bauxite

As it was noted, diasporic bauxite ores (diaspore is naturally hydrophilic) have a low Al/Si mass ratio, and an extensive comminution has to be performed on the ore in order to liberate value and gangue minerals and prepare them for selective interaction with reagents (direct and reverse flotation) ( Wen-li et al., 2014;Kurusu et al., 2009).
