ABSTRACT A collector composition, useful for the recovery of metal-containing sulfide minerals, sulfi- dized metal-containing oxide minerals, metal-containing oxide minerals and metals occurring in the metallic state from ores in a froth flotation process, comprises two collectors. One collector is an organic compound containing at least 4 carbon atoms and one or more monosulfide units, wherein the carbon atoms to which the sulfur atoms are bound are aliphatic or cycloali- phatic carbons. The other collector is preferably an omega-(hydrocarbylthio)alkylamine, S-(omega-aminoalkyl)- hydrocarbyl thioate, N-(hydrocarbyl)-alpha,omega-alkane- diamine, (omega-aminoalkyl)hydrocarbon amide, omega- -(hydrocarbyloxy)alkylamine, omega-aminoalkyl hydrocar- bonoate , omega-(hydrocarbylthio)-alkylamide or mixture thereof. 34,046-F
