ABSTRACT OF THE DISCLOSURE The invention is primarily directed to the production of a substantially iron free alumina-silica product and substantially iron free aluminum chloride from bauxites, bauxitic clays and kaolinitic clays wherein the feed material to an agglomeration stage is selected to contain a minimum of about 20% kaolinite mineral. The agglomerates are so formed to produce a product that is preferably at least minus 6 mesh plus 200 mesh and in a subsequent calcination stage the calcined agglomerates have a bulk density of preferably 0.8 to 1.3. In a subsequent differential iron chlorination stage a substantially iron free alumina-silica product is produced and in a subsequent mass chlorination stage substantially iron free aluminum chloride is produced.
