OPTIMIZATION OF AIR-INJECTION SPARGERS FOR COLUMN

In column flotation operations, Sparger sparging devices are employed in column flotation operations to generate small bubbles into the cell with the aim to carry the the desired mineral to the surface for later be recovered and proceeded. However, field studies suggest that air injector sparging systems are not always optimized.

Froth flotation Wikipedia

Froth flotation depends on the selective adhesion of air bubbles to mineral surfaces in a mineral/water slurry. The air bubbles will attach to more hydrophobic particles. The attachment of the bubbles to the surface is determined by the interfacial energies between the solid, liquid, and gas phases.

In froth flotation, air is bubbled through an

In froth flotation, air is bubbled through an aqueous solution or slurry to which a foaming agent (soap) has been added. The air bubbles carry finely dispersed solids and hydrophobic materials such as grease and oil to the surface where they can be skimmed off in the foam an ore-containing slurry is to be processed in a froth flotation tank at a rate of 300 tons/h.

Minimizing bacterial biofilm in water using froth

Therefore, it is suggested that a froth flotation treatment be followed by shock chlorination and shock de-chlorination. Chlorination is a well-known technique in water treatment but the de-chlorination is left to occur naturally and, in many cases, to leave an intended residual chlorine content at the point of use.

The results show that the concentrate flow rate, yield and product ash content increased with air flow rate. This trend is expected since the available bubble surface area increases with air flow rate.
