Flotation Circuit an overview ScienceDirect Topics

1 Introduction. Flotation circuits are a common technology for the concentration of a broad range of minerals and wastewater treatments. Froth flotation is based on differences in the ability of air bubbles to adhere to specific mineral surfaces in a solid/liquid slurry. Particles with attached air bubbles are carried to the surface and removedget price
