Abstract
294,681. Spence & Sons, Ltd., P., Craig, T. J. I., and Kirkham, A. April 28, 1927. Silica.-Siliceous residues obtained in the acid treatment of silicates decomposable by mineral acids with removal of alumina, iron oxide, alkalies and alkaline earths are dissolved in sodium or potassium carbonate solution, at about 160' C. and under 801b. pressure if the carbonate and silica are about in molecular proportions and at lower temperatures and pressures if more carbonate is used. Titanium oxide, if present in the original materials, for example clay or bauxite, remains in the residue. The solution of silicate is decomposed by passing carbon dioxide into it or by adding bicarbonate solution, to precipitate silica in a flocculent form. The precipitate is washed with water and acid, to remove alkali, and finally with water and may be dried and sieved.
