Primary Separation Cells
However, this is often the quickest way to regain control of a poorly performing circuit. Oil sands feed with a high fines content needs more dilution and more residence time than a good quality ore. It is therefore normal to expect reduced production when processing a lower quality (or low grade) oil sands deposit. 2. Increase process …

Column Flotation Cells
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

Flotation
Flotation is widely used to separate valuable minerals from the rock and fine coal particles from clay, silt, shale, and other ash-producing matter. It is usually preceded by crushing and finely grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.
