1. Introduction. Flotation is a complex process whose performance is a result of the interaction of several subsystems, involving particle, chemical, operational, and machine factors [1]. It exhibits high dimensionality, which makes modeling and optimization very challenging [2,3].

Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
