Abstract
Method for obtaining a fluorspar concentrate, by flotation by foam of an aqueous pulp of a fluorspar ore containing a fluorspar sensor, in which a fluorspar concentrate containing at least 97% in weight of this body, characterized in that it comprises (1) the preparation of an aqueous pulp suitable for flotation by foam and containing: (a) a natural ore of fluorspar containing less than 0.1 part by weight of iron, calculated on ferrous sulfate, per 1000 parts by weight of natural ore and have appreciable amounts of gangue materials and metal sulfides; (b) a water-soluble iron compound, preferably ferrous sulfate, in an amount such that the pulp contains from 0.1 to 0.4 part by weight of dissolved iron, calculated as ferrous sulfate, per 1000 parts by weight of natural ore; (c) a fluorspar collector consisting of one or more saturated fatty acids or soaps thereof alone or mixed with one or more unsaturated fatty acids or soaps thereof, in a proportion of up to 70% by weight, based on the weight of the mixture; and (d) at least one depressor for gangue materials, which is a silicate or alkali metal metasilicate, or quebracho; (2) conditioning the aqueous pulp by heating it to its boiling point while maintaining the ph thereof between about 8 and about 9, preferably between about 8.4 and about 8.8. (3) subjecting the conditioned pulp to flotation by foam, producing a foam rich in fluorspar; and (4) the recovery of a concentrate, enriched in fluorspar, from the foam.
