    • The present invention relates to improved process for beneficiating an ore-containing sulfide material. In particular, the process is useful for beneficiating ores and recovering metals such as gold, copper, lead, molybdenum, zinc, etc., from the ores. In one embodiment, the process comprises the steps of: (1) forming a slurry comprising at least one crushed mineral-containing ore, water and a collector which is a mixture of (A) at least one metal salt of a phosphorus acid represented by formula (I), wherein each R1 is independently a hydrocarbyl, hydrocarbyloxy or hydrocarbylthio group having from 1 to about 18 carbon atoms, each X is independently oxygen or sulfur, and the lowest oxidation state of the metal is plus two, and (B) at least one thio compound comprising (i) at least one dithiocarbamate represented by formula (II), wherein each R2 is independently hydrogen, a hydrocarbyl group having from 1 to about 18 carbon atoms, or R2 taken together with R3 and the nitrogen atom form a five, six or seven member heterocyclic group; each R3 is independently a hydrocarbyl group having from 1 to about 18 carbon atoms, or R3 taken together with R2 and the nitrogen atom form a five, six or seven member heterocyclic group; and R4 is a hydrocarbylene group having from 1 to about 10 carbon atoms, (ii) at least one thionocarbamate represented by formula (III) wherein R5 and R6 are hydrocarbyl groups having from 1 to about 18 carbon atoms or mixtures of (i) and (ii); (2) subjecting the slurry from step (1) to froth flotation to produce a froth; and (3) recovering a mineral from the froth.
