Abstract

Aluminiferous materials having a high percentage of silica, such as kaolins, clays, and certain bauxites, and not more than 12 per cent of iron are preferably roasted and then treated with hydrochloric acid to obtain a solution of chlorides which after separation from undissolved silica &c., is treated with calcium aluminate to precipitate aluminium hydroxide and obtain a calcium chloride solution. A part of the hydroxide precipitate is converted to a sodium aluminate solution from which pure aluminium hydroxide may be obtained, whilst the remainder is mixed with the calcium chloride solution, the mixture evaporated to dryness, and after optional pulverization, heated in the presence of steam to obtain hydrochloric acid for re-use in dissolving more raw material and calcium aluminate for re-use in precipitating aluminium hydroxide. In a modified process the chloride solution is precipitated with a mixture of calcium aluminate and calcium carbonate, the resulting mixture of aluminium hydroxide and calcium chloride solution dried, pulverized, and heated in the presence of steam to obtain hydrochloric acid for re-use and calcium aluminate, a part of the calcium aluminate is treated with sodium carbonate to obtain calcium carbonate and sodium aluminate, the other part of the calcium aluminate and the calcium carbonate is re-used for precipitating the chloride solution, and aluminium hydroxide is recovered from the sodium aluminate solution, as by treatment with carbon dioxide to obtain sodium carbonate for treating fresh quantities of calcium aluminate. Undissolved silica recovered from the chloride solutions may be mixed with Portland cement to adapt it for use in concrete structures below the surface of water.ALSO:Silica obtained as a residue when aluminiferous materials such as Kaolin, clay, or bauxite, preferably previously roasted, are treated with hydrochloric acid, is dried at a low temperature and then mixed with Portland cement, say in the proportion of 3 parts cement to 1 part silica, to adapt the cement for use in concrete structures below the surface of water.
