    Abstract: Rutile is recovered from copper ore tailings by means of a froth flotation process comprising: (a) flotation of sulfides and carbonates at a pH of about 9 to 10, using sodium isopropyl xanthate and sodium oleate as collectors, and detrine as rutile depressant, and (b) flotation of rutile from the resulting tailings at a pH of about 2 to 3, using hydrofluoric acid as a rutile selectivity-assisting agent and water-soluble petroleum sulfonate as rutile collector.

    Abstract: A phosphate ore flotation process subjecting a phosphate ore containing carbonate mineral impurities to froth flotation in the presence of phosphate depressants, said depressants are alkyl phosphonic acids, and a carbonate collector, said collector is fatty acids, removing the separated carbonate minerals from the overflow, and recovering the phosphate value in the underflow. The process of the present invention can be performed either prior to or after the separation of siliceous matter from phosphate minerals by methods known in the art.

    Abstract: A method for separating copper sulphides from lead sulphides contained in particulate copper lead sulphide concentrates by a flotation process in which an aqueous alkali metal silicate-alkali metal dichromate reagent solution is added in the flotation step to depress the lead bearing sulphides. The copper lead sulphide concentrate may be obtained from a complex copper-lead-zinc ore, in which case the majority of the zinc is first removed by conventional flotation techniques and the copper lead sulphide concentrate treated with activated carbon prior to addition of the silicate-dichromate reagent solution.
