    摘要: 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.
