The Definitive Guide to Flotation Separation Fote

2021-6-8  What is flotation separation The flotation separation mainly refers to froth flotation, which is based on the difference in physical and chemical properties of the surface of minerals, using the buoyancy of bubbles in the ore pulp to achieve separation.
