The Direct Flotation Reactor (DFR) is a flotation cell that works on the principle of preventing the formation of a froth and froth slurry interface. Independent bubbles are removed from the collection zone in a gas phase/slurry phase. ... with no step height between cells. Being a low air system, the DFR has enhanced selectivity and like the ...
It has been found that changes in rheology of mineral slurries influence the hydrodynamics within flotation cells and therefore various flotation sub-processes including gas dispersion and particle–bubble ... A copper–gold ore with low clay content was ... The mill discharge was then transferred to a 3.0 L Agitair flotation cell.
Flotation cells COPPER FLOTATION MACHINE, FROTH FLOTATION CELLS, FLOTATION CELL Flotation machine, in the ore dressing industry, mainly used for separating copper, zinc, lead, nickel, gold and other Non-ferrous metal, can also be used for Ferrous, non-metallic crude and selected.

However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity.
