ABSTRACT:
A collector composition useful for the recovery of metal values from metal 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 cycloaliphatic carbons. The other collector is preferably an omega-(hydrocarbylthio)alkylamine, S-(omega-aminoalkyl)hydrocarbyl thioate, N-(hydrocarbyl)-alpha, omega-alkanediamine, N-(omega-aminoalkyl)hydrocarbon amide, omega-(hydrocarbyloxy)alkalamine, omega-aminoalkyl hydrocarbonate or mixture thereof. The collector composition floats a broad range of metal values including sulfide ores, oxide ores and precious metals.
