Function of k for different particles in the flotation cell and thus eq 6 can be equal to dr r n dt f 7 the ultimate recovery r distribution of flotation rate constant fk and order of flotation kinetics n in eqs 6 and 7 can be determined from the experimental data of r versus t

Flotation frothers what is the function of frothers the function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form

Mineral flotation in mechanically agitated vessels cells involves complex interaction between bubbles particles and the liquid phase ideally just enough power input from the impeller is needed to so that the frequency of particlebubble collision and attachment is maximised while at the same time detachment events are minimised

Flotation in mineral processing method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is the surfaces are either repelled or attracted by water the flotation process was developed on a commercial scale early in the 20th century to
