Abstract: Flotation processes are provided, wherein a vinyl sulfonic acid polymer or an allyl sulfonic acid polymer is added to the pulp in a minor amount as a depressant for constituents which preferably should be floated to a minimum degree. Thus the polymers are effective barite-depressants in the flotation of fluoride minerals and rare earth carbonates. Also the polymers are useful as monazite depressants.

Abstract: A process is provided for the flotation of ores, wherein esters of orthophthalic acid or maleic acid with C.sub.8 -C.sub.14 alcohols or oleyl alcohol are used as collectors, together with the usual fatty acid type collectors, thus permitting important savings in the use of this latter component. Particular advantages are so obtained in the flotation of phosphate ore and of magnesium-containing minerals.

Abstract: A process is provided for the flotation of ores, wherein compounds of the formula RO-(C.sub.x H.sub.2x O).sub.n CH.sub.2 COOM, wherein R is an aliphatic residue of 8-18 carbon atoms or an alkylaryl residue having 6-12 carbon atoms in the alkyl moiety, n has an average value of 0-10 and x has a value of 2 or 3, and M is a monovalent cation, are used as collectors, together with the usual fatty acid type collectors, these collector mixtures possessing synergistic properties. Also collector mixtures for use in such a process are provided.
