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
