    Abstract: The present invention provides a new collector for use in the froth flotation of metal values from their ores. The collector comprises a synergistic mixture of alkyl xanthogen alkyl formates and dialkyl thionocarbamates, and yields metal recoveries superior to that achieved with either collector alone. According to the present invention the novel collector for use in froth flotation comprises a mixture of alkyl xanthogen alkyl formates having the general formula: ##STR1## wherein R is a branched or straight chain alkyl substituent having 1 to 6 carbon atoms, and R' is selected from the class consisting of ethyl and methyl; anddialkyl thionocarbamates having the general formula: ##STR2## wherein Y is a branched or straight chain alkyl substituent having 1 to 6 carbon atoms, and Y' is selected from the class consisting of ethyl and methyl.
