The different between Bulk Flotation and Selective Flotation is: In Bulk Flotation, in the concentrate you have all ores that you have in your slurry. In Selective Flotation by the action of reactive you can have in the concentrate one ore that you want. The quality of concentrate its better than Bulk Flotation.

Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner's mistake made by non-operating types. You do not need to pump anything in the lab. In selective flotation, less is more!
