Kinetics of indium polyphosphate flotation

The purpose of the paper was to clarify the mechanism of interaction of particles with air bubbles in simple flotation act in connection with expanded possibilities of ''ion flotation'' application for extraction of valuable components from diluted hydrometallurgical solutions, liquid wastes and industrial effluents of different industrial processes. A study was made on kinetic regularities of indium flotation by means of inorganic metaphosphates functioning as electronegative ligands, and some salts of long-chain amines. Sulfate indium solutions (pH <= 5) containing 10-4 g-ion/dm3 of the metal were the objects of the investigation. It is shown that the form of kinetic lines is determined by concentration of a collecting agent introduced into indium metaphosphate solutions. The suggested model of flotation is true for the simple act of particles of low-soluble compounds and air bubbles interaction not complicated by the surface (laminar) coagulation of particles of low-soluble compounds with one another on the mobile interface of liquid-gas phases
