Flotation is a mineral separation process done in the water medium It is based on the difference in the surface properties of the mineral and gangue The surface of the selected mineral is made hydrophobic water repellent by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system and collected as froth whereas the hydrophilic
