Abstract
WHILE deposits of bauxite, that is, of the aluminium hydroxides gibbsite and diaspore, are greatly in request as sources of aluminium, bauxitic clays are also of considerable value for the lining of high-temperature furnaces. It is well known that under tropical conditions of weathering, especially where the surface-waters are alkaline, rocks of very varied nature, containing aluminium silicates, yield bauxite rather than kaolin. Any ferruginous matter forms at the same time lateritic crusts. Laterite, indeed, as Sir Thomas Holland pointed out for India, is at times rich in aluminium hydroxide.
