ABSTRACT This invention concerns a novel composition which is useful as a collector for the recovery of nonferrous metal-containing sulfide minerals and sul- fidized metal-containing oxide minerals from ores in a froth flotation process. The novel composition com- prises (a) a hydrocarbon containing one or more mono- sulfide units, wherein the carbon atoms to which the sulfur atom(s) are bound are aliphatic or cycloali- phatic carbon atoms, and the total carbon content of the hydrocarbon portion is such that the hydrocarbon has sufficient hydrophobic character to cause the metal-containing sulfide mineral or sulfidized metal- -containing oxide mineral particles to be driven to an air/bubble interface; and (b) an alkyl thiocarbonate, a thionocarbamate, a thiophosphate, or mixtures thereof. 34,276-F
