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.

The Flotation Cell is aerated to produce bubbles and agitated to keep the solids particles in suspension in the pulp. A flotation cell is an 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 ...
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector.
