Abstract

The sulphonation of fatty acids or fatty oils is effected by heating the acid or oil with concentrated sulphuric acid, the mixture being kept stirred. Details of the weights of the reacting substances and the time and temperature are given for the sulphonation of the following:--oleic acid, a mixture of equal parts of oleic acid and palm oil, castor oil, cotton seed oil, linseed oil, olive oil, and pea-nut oil. Specifications 19855/14 and 19856/14, [both in Class 82 (ii), Washing granular &c.], are referred to.ALSO:In the froth flotation concentration of oxidized minerals an organic sulphur-containing carbonic acid compound, for example a xanthate, and a sulphonated fatty acid or fatty oil are used conjointly as flotation agents, preferably also with a soluble frothing agent, e.g. cresylic acid. The sulphonated compounds of the following acids and oils are referred to:-oleic acid, equal parts of oleic acid and palm oil, castor oil, cotton-seed oil, linseed oil, olive oil, and pea-nut oil; the products are used with potassium ethyl xanthate or potassium amyl xanthate, cresylic acid, and sodium silicate, with or without palm oil, in the flotation of an oxidized copper ore. The sulphonation is effected by heating the acid or oil with concentrated sulphuric acid, the mixture being kept stirred. Details of weights of reacting substances, temperature, and time are given in each case. Specifications 19855/14 and 19856/14, [both in Class 82 (ii), Washing granular &c.], are referred to.
