Abstract

515,606. Concentrating ores. SMIDTH & CO. AKTIESELSKABET, F. L. Sept. 12, 1938, No. 26560. Convention date, Sept. 10, 1937. [Class 82 (ii)] Minerals are separated from oxidized ores by froth flotation using as collecting agent an aqueous emulsion of a fatty acid stabilized by a sulphonated oil or fat or by a sulphonated fatty acid which acid occurs in a fat or oil either free or in the form of an ester. The emulsion, which may be made for example, with oleic acid or fish oil fatty acids, preferably has an oil to water ratio of between 1:10 and 1:30, and about 5-7 parts of sulphonated oil or acid are added for each 100 parts by weight of the fatty acid. Sulphonated products which may be used include sulphonated tea seed oil, castor oil, olive oil, cora oil, cod oil, neats foot oil. and sulphonated oleic acid. The process is of particular application in the flotation of calcite from argillaceous limestones, marls, chalks &c. to give a raw material suitable for use in cement manufacture; the concentration of the calcite being carried out with one of the collecting emulsions and with a frother, e.g. a mixture of aliphatic alcohol, boiling between about 152 and 162‹C., obtained with methanol by the catalytic hydrogenation of carbon oxides, the collecting agent being preferably added in stages. The frother may be emulsified with sulphonated alcohol. Reference is also made to the use as collectors of fatty acid emulsions stabilized by sulphonated alcohols. Specification 426,423 is referred to.
