The flotation process is a complex interaction between the physicochemical characte- ristics of the species involved and the hydrodynamic and operating conditions in flotation cells. Efficient cell design requires knowledge about the power to be provided and the time to be spent in the cell by each one of the phases.

Definition of flotation cell. Appliance in which froth flotation of ores is performed. It has provision for receiving conditioned pulp, aerating this pulp and for separate discharge of the resulting mineralized froth and impoverished tailings. Types of cell include (1) agitation (impeller, and splashing, now obsolete); (2) pneumatic (in which ...

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.
