Abstract

Ores are concentrated by froth flotation by the use, in conjunction with a collecting agent, of a frothing agent which comprises a hydrocarbon and one or more aliphatic alcohols having from 7-10 carbon atoms and a boiling point between about 133 and 250 DEG C. The alcohols which may be used include the primary and secondary and in some cases the tertiary heptyl, octyl, nonyl, and decyl alcohols, and preferably a mixture containing octyl and nonyl alcohols and a preponderance of heptyl alcohol is employed. The hydrocarbon preferred is either "naphtha," i.e. a saturated fraction obtained from petroleum oils and boiling between 300 and 500 DEG F., or a hydrocarbon of the terpene series, e.g. dipentene, but the use of benzol, toluol, xylol, and solvent naphtha is also referred to. The amount of alcohol in the mixture may vary from 50-90 per cent. The concentration of a lead ore is described, the frothing agent consisting of a mixture of alcohols including methyl hexanol, di-methyl hexanol, methyl heptanol and di-methyl heptanol and either naphtha or dipentene, and the collecting agent being ethyl xanthate. The use of still bottoms from the distillation of petroleum hydrocarbons, as claimed in Specification 441,976, is excluded from the scope of the invention.
