Abstract

554,593. Aluminium compounds. ENGLISH CLAYS. LOVERING, POCHIN & CO., Ltd., DAVIES, R. J., DERING, H. O., and PARKER, T. W. Dec. 1, 1939, No. 31287. [Class 1 (iii)] In the preparation of alumina from clay by a method such as that described in Specification 554,591 in which ammonium alum is obtained by sintering clay with ammonium sulphate ammonium alum is decomposed by passing a solution of ammonia and ammonium sulphate through a stationary mass of the damp crystals. Specification 120,550, [Class 1 (iii)], also is referred to.
