Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.Application of Ore froth flotation 1.Ore froth flotation can be widely used in the beneficiation of non ferrous metals, black metals and nonmetals. (2) When the impeller of the lead zinc Ore froth flotation begins to rotate, negative pressure is formed, making the air and pulps at the bottom and middle part of the tank enter the mixing zone.
