Froth flotation of calcium borate minerals

Particles of a calcium borate mineral, such as colemanite or ulexite, are recovered from an ore by a froth flotation process using a dialkyl sulphosuccinate as collector. Suitable dialkyl sulphosuccinates include sodium or ammonium dinonyl sulphosuccinate, sodium or ammonium di-isodecyl sulphosuccinate, and sodium or ammonium dilauryl sulphosuccinate.

Froth Flotation Bubble Collision

 · The complexity of froth flotation may be reduced by considering the relative motion of a single bubble and a single particle as shown in figure 1. The reduction of the system to two particles is of course a simplification, but it is also a practical and convenient place to start an analysis of the complex hydrodynamic process of flotation.

Effectively enhancing recovery of fine spodumene via …

 · Therefore, finding ways to reduce the negative effects of fine spodumene particles in the spodumene froth flotation process is vital. Thus far, research on this has focused on two aspects. The first type focused on modifications of the flow of the desliming process to improve quality of slurry and particle size [ 17 ].

Jameson cell

A conventional flotation cell has problems with recovering fine particles at high grades due to the entrainment of gangue minerals in the froth. The high throughput of the Jameson Cell means that the froth is produced in a small surface area so it is economic to apply froth washing to all cells [47]

The link between particle size and froth stability

 · However, tailings material is generally comprised of fine particles, which poses a challenge for its reprocessing using froth flotation due to reduced recoveries of these particle sizes. In addition, there is some debate as to the effect that these fine particles have on the froth stability, which in turn is linked to mineral recovery.

Fine particle flotation

 · The theory of fine particle flotation is not well defined and our understanding of the behaviour of fine particles in flotation is still very limited. It has been suggested that the optimum conditions for fine particle flotation may be quite different from those for the coarse particles (Trahar, 1981; Adorjan, 1982).
