Abstract

A sulpho-fatty acid compound produced by the action of a sulphonating agent on a free unsaturated fatty acid containing at least 12 carbon atoms is used as a collecting agent in ore concentration. The compound may be wholly or partially neutralized with a base such as sodium hydroxide or pyridine. For example, oleic acid in the form of red oil may be sulphonated by stirring with 5, 10, or 25 per cent of its weight of concentrated sulphuric acid; linoleic acid and ricinoleic acid may be treated similarly with 10 and 5 per cent respectively of sulphuric acid; erucic acid may be melted and stirred with 5 per cent of sulphuric acid; the stirring in each case being continued until the mixture is cool.ALSO:The separation of minerals from their ores is effected by mixing an aqueous pulp of the ore with an insoluble and unsaponifiable oil, e.g. fuel oil, and a sulpho-fatty acid compound produced by the action of a sulphonating agent on a free unsaturated fatty acid containing at least 12 carbon atoms, and then subjecting the pulp to a separating treatment such as froth flotation, tabling, or hydraulic classification. The sulpho-fatty acid compound produced as set out above may be wholly or partially neutralized with an alkali such as sodium hydroxide or pyridine. For example, oleic acid in the form of red oil may be sulphonated by stirring with 5, 10, or 25 per cent of its weight of concentrated sulphuric acid; linoleic acid and ricinoleic acid may be treated similarly with 10 and 5 per cent respectively of sulphuric acid; erucic acid may be melted and stirred with 5 per cent of sulphuric acid; the stirring in each case being continued until the mixture is cool. The process is described with reference to the concentration of both metallic and non-metallic minerals, copper sulphide ores, oxidized copper ores, calcium phosphate ores, limestone ores, barite ores, fluorspar ores, and kyanite being specifically referred to. The ore is preferably deslimed, and the pulp may be made alkaline, e.g. with lime; when concentrating by froth flotation, a frother such as a solution of crude rosin residue in kerosene may be added.
