Novel composition which is useful as a collector for the recovery of nonferrous metal-containing sulfide minerals and sulfidized metal-containing oxide minerals from ores in a froth flotation process. The novel composition comprises (a) a hydrocarbon containing one or more monosulfide units, wherein the carbon atoms to which the sulfur atom(s) are bound are aliphatic or cycloaliphatic 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. |
