Flotation Cell-Pre-treatment-
Description. Flotation cells is widely applied for metal and non-metal separation processing from roughing, cleaning to scavenging. There are pneumatic &mechanically agitating flotation cells. Optionally, the floatation cell is able to suck ore pulp into the cell due to negative pressure created in the enclosed space in the propeller with a cover.

Next the pulp undergoes flotation in two tank cells in order to remove other impurities. Once these contaminants are removed, the pulp is pumped to its third and final flotation stage where other reagents are added to concentrate the desired non-ferrous metal. The Process Flowchart is presented in figure 1.

Hydrodynamics of froth flotation and its effects on fine and …
Unlike single-phase liquid, flotation pulp is a complex three-phase system of water, solid, and gas. The presence of dispersed gas and solid phases makes the fluid flow patterns in flotation cells non-uniform and complex (Koh and Schwarz, 2007, Schwarz et al., 2016). Therefore, flotation hydrodynamics is a broad term, and the effects of the ...

Numerical modelling of non-Newtonian slurry in a mechanical flotation cell
Flotation cell. As with the PBT, the predicted cavern was defined as an isosurface of γ = τ y / μ y. For 40 and 50 wt% slurries, μ y was set to 10 kg / m s, as this corresponded to γ < 0.2 s - 1, but for the 60 wt% slurry, μ y was made to equal 40 kg / m s due to the high yield stress.
