2021-7-20  In the practice, the flotation method, gravity separation method and combined beneficiation method can be used for copper - lead - zinc sulfide ore. Among them, the flotation method has become the main separation method of copper, lead and zinc sulfide ores because of its good separation effect on various complex polymetallic co-biogenic minerals.

Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasons.
