Des Clifford reviews some of the developments, particularly in cell and mechanism design, in this important area of mineral processing.
Flotation is, arguably, the most important mineral separation technique and represents one of the more challenging applications of surface chemistry. Inefficiencies in flotation translate into both an enormous loss of revenue and an unnecessary waste of these reserves. This is particularly important in the flotation of the finer particle size ranges where flotation efficiency is often poor.
The flotation process is controlled by the thermodynamics, kinetics and hydrodynamics of the system. Fundamental aspects include:
