A significant review of froth stability in mineral flotation

Flotation was first performed in 1860 (Arbiter, 2000) and is a technology that utilizes the differences in physicochemical properties of various mineral surfaces to achieve specific separation (Wills and Munn, 2005), as depicted in Fig. 1.This process involves hydrophobic particles adhering to air bubbles being transported to the froth layer, whereas hydrophilic …

Flotation

Flotation of fine particle (<37 μm) and ultrafine particle (<8–13 μm) is a key challenge. Feed in flotation consists of wide range of particle size, therefore, flotation column needs to have wider bubble size to target fine as well as coarse size particles [13, 14]. So, flotation of fine particles is one of the major challenging tasks.

A critical review on the flotation of calcium-containing minerals

Froth flotation is the most effective method to separate and enrich refractory calcium-containing minerals. Because the calcium ions in the mineral lattice are the same, they have similar surface chemical properties and dissolution characteristics (solution chemical properties) in the slurry environment [29], [30], [31], resulting in a lack of selectivity in the adsorption of flotation ...

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp ...
