US20090008301A1 Methods of Increasing Flotation Rate

Methods of increasing the rate of separating hydrophobic and hydrophilic particles by flotation have been developed. They are based on using appropriate reagents to enhance the hydrophobicity of the particles to be floated, so that they can be more readily collected by the air bubbles used in flotation. The hydrophobicityenhancing reagents include low HLB surfactants, naturally occurring
