  • Bauxite

    Bauxite is the main raw material used in the commercial production of alumina (Al 2 O 3) and aluminium metal globally, although some clays and other materials can be utilised to produce alumina. Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium.

  • Mechanochemical treatment of high silica bauxite with .

    To quantify the effect of milling on soda consumption, the soda/silica ratios in Fig. 3 have been compared with soda/silica ratios of unmilled bauxite digested using similar concentrations of CaO. Since different bauxites and liquors were used in the two tests, the soda consumption figures for each set of data are normalised to a base case .
