Selective Flotation - Mineral Processing Metallurgy

2015-9-17  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! Over 2 years ago I wrote about the intricacy and importance of mass pull in a plant VS laboratory. I need to restate I suppose that flotation

Flotation processes are based on the different surface wettability properties of materials Wang et al., 2015. In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.
