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.
