In the mechanical flotation cells the feed can be introduced directly to the impeller zone from the side as in a Denver-style Sub A sub-aeration machine.. A centrally located paddle-wheel type impeller generates a rotating pulp vortex which extends between two stationary elements the sand-pipe located at the top of the cell, and the draft tube located at the bottom of the cell.

Optimizing Flotation Cells. H ow a flotation cell works . 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 high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
