High Pressure Grinding Rolls (HPGR) is rarely considered as lateritic bauxites are too soft to warrant this technology. Only for hard diasporitic bauxite, where digestion feed sizes of P80 -75 µm are required would it ever be considered. Rod and ball mills can readily handle bauxite on account of its very soft nature. However, it is the

3, which is available as a raw material for grinding, is obtained from bauxite via conventional melting methods [MUEL02, N.N.1]. For the manufacture of sintered bauxite corundum, ground raw bauxite is mixed with water, binding materials and compacting auxiliary agents. The pasty mass is then extruded, cut into lengths and finally sintered.
