Research On Copper-molybdenum Ore Flotation Separation Process

Most copper-molybdenum ores adopt the mixed flotation-copper-molybdenum separation process, because molybdenite and chalcopyrite have similar floatability and serious concomitant, and this process has lower cost and simpler process.In general, the mixed collectors of flotation machine use xanthate (butyl xanthate), auxiliary collector hydrocarbon oil (kerosene), terpineol oil as foaming agent, lime and water glass as regulators.…
