Flotation kinetics (from the Greek Kintiks driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, i.e. R = f (t). It allows a quantitative description of the flotation process in time.

The improved equation of flotation kinetics with delay. 3. For many minerals the flotation kinetics cant be described only by an exponential dependence, since there is a delay due to the surface properties of minerals. For such minerals dependence R = f ( t ) has a pronounced S shaped form with a delay (Fig. 2).

Developments in flotation reagents have made the recovery of a wide variety of oxide, carbonate and silicate minerals by flotation a more much effective and economic process. Aeration is added through spargers at the bottom of the flotation cell. The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow. SGS has extensive experience conducting reverse flotation for

flotation process, in mineral treatment and mining, process for concentrating the metal bearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Flotation is that process wherein, finely ground minerals are made hydrophobic so that they can be attached to air bubbles and separated in a froth from the rest of the slurry. Most flotation separations are based on the selective adsorption of amphi pathic organic reagents (called collectors) at mineral/water interfaces. Although flotation is concerned to a large extent with the specific adsorption
