Bauxite Beneficiation: An Approach to Value Addition in Mining

Jul 2, 2021Our experience shows that in low silica gibbsitic bauxite of Guinea, it is sometimes beneficial to remove fines of below 5-10 mm sizes by dry processes, to decrease the goethite & boehmite contents and improve moisture before export. This process may be useful for those deposits/mines having low alumina and high goethite content.

The combination of these two steps indicate that a two-stage beneficiation process is advantageous. First the mine-run shales are separated by crushing and screening (size reduction) into a rich coarse fraction and a lean fine fraction. Then the rich coarse fraction is further upgraded by heavy media (sink-float) separation.
