Basic Principle of Froth Flotation Process The process of froth floatation starts with the Comminution process, in which the surface area of the ore is increased First of all, the ores are crushed into very fine powdersized particles and mixed with water The mixture obtained is called SlurryFlotation separation is mainly used for removing particulates from aqueous dispersions It is widely used for ore beneficiation and recovering valuable materials This paper reviews the hydrodynamics of flotation separations and comments on selected recent publications Units are distinguished as cells of ideal and nonideal flow A brief Hydrodynamic aspects of flotation separation De Gruyter
