ABSTRACT:
This invention relates to a 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) an organic compound containing one or more monosulfide units wherein the sulfur atom(s) are bound to aliphatic or cycloaliphatic carbon atoms, and the total carbon content of the compound is such that the compound has sufficient hydrophobic character to cause 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 thionacarbamate, a thiophosphate, or mixtures thereof.
