Abstract

Flotation flotation process, to obtain a concentrate enriched with fluorspar, with a proportion of at least 97% of a raw fluorine flute containing, in addition to the fluorspar, appreciable quantities of gangue minerals and metal sulphides, characterized why an aqueous pulp is prepared by mixing the ground raw mineral with water and, as a collector for the fluorspar, one or more saturated fatty acids or soaps thereof, or a mixture of one or more saturated fatty acids or soaps thereof , and one or more unsaturated fatty acids or soaps thereof, in which mixture the content of saturated fatty acid or soap thereof, is at least 40% by weight and, as a depressant for the minerals of the gangue, one or more alkali metal silicates or metasilicates; heat the pulp to its boiling point, with stirring, while maintaining the pulp at a pH between 8 and 9, if necessary, sort the pulp to prepare a pulp of a particle size suitable for flotation; and subjecting the pulp to flotation by foam, thus producing a foam rich in fluorspar, and recovering the aforementioned concentrate enriched in fluorspar from the foam.
