The main contaminants of kaolin are quartz and mica (10-45%), as well as iron oxide (1-10%) [4]. The extraction of alumina from kaolin has been widely investigated with a range of acid and alkali hydrometallurgical processes. Leaching of aluminium from calcined kaolinitic clays with HCl or H2SO4 solutions is proposed with the sequent ...
