For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not

Batch Laboratory Flotation Testing starts from the 3 fundamental types of flotation processes or methods which can be classed as either. Bulk flotation; Differential flotation; Sequential flotation; While all flotation processes are selective or differential in that one mineral or group of minerals is floated away from accompanying gangue, bulk flotation generally refers to separation of

Froth flotation is based on the ability of chemical reagents, called collectors, . attachment of the modified mineral particles to air bubbles in the flotation cell.
There are a number of cells able to be used for the flotation of minerals. these include flotation columns and mechanical flotation cells. The flotation columns are used for finer minerals and they typically have a higher grade and lower recovery of minerals than mechanical flotation cells. The cells in use at the moment can exceed 300 m 3. This is done as they are cheaper per unit volume than smaller cells
froth flotation cells. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.
