Abstract
1,243,112. Treating ores. CANADIAN PATENTS & DEVELOPMENT Ltd. 30 April, 1969 [7 June, 1968], No. 22132/69. Heading B2H. Siliceous and/or phosphatic materials are separated from iron ore by forming an aqueous mixture containing the ore in particulate form, a surface active conditioning agent consisting of a sulphonic acid, a fatty acid and/or a water soluble salt thereof, and a hydrocarbon oil, agitating the mixture to form an agglomerate oil phase and a residual aqueous phase, one of the phases being rich in iron and the other in siliceous and/or phosphatic material, and separating the phases. The pH of the mixture may, if necessary, be adjusted so that such phases are formed. The ore may be finely ground either before or during mixing with water. Specified conditioning agents are oleic acid, linoleic acid, tall oil and their soluble alkali metal or ammonium salts. An amine conditioner, e.g. one derived from pine resin acid, may he employed in small amounts along with sulphonic or fatty acid. An iron depressant, e.g. dextrin, may be added when operating at an elevated pH. Examples are given.
