frothers (e.g. adsorb frother) thus changing both pulp and froth zone properties. A prime objective of this review paper is to explore how frothers and particles interact to affect the sub-processes occurring in the pulp and froth zones in order to better understand the effect of these issues in mineral flotation.

An inherent limitation with the flotation of fine partcles in conventional cells is recovery of hydrophilic (gangue) particles by mechanical entrainment in the water reporting to the froth. The method of minimizing entrainment is to create a 5-3Ocm thick froth at the slurry surface. The froth permits the gangue to drain back to the pulp while

The ore being treated has both free gold and gold associated with pyrite. Quite simply stated, if the pulp density is not maintained at 30% or higher by weight, it is very difficult to keep the coarser free gold into the froth phase. Copper sulfate is often used as an activator for promoting free gold flotation.

Apr 25, 2014· Abstract. Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase, transported into the froth phase, and surviving as bubble-particle aggregates into the overflow.

Description. Flotation feed density is an operating parameter which is currently not well understood. Most models of flotation only incorporate its effect on particle residence time, but it is likely to have additional effects within both the pulp and froth phases of the machine.

Kongolo, 2003), attention has been focused on the effect of chem-ical variables on environmental desulphurization of different mine tailings. In the present study, the effects of operation conditions such as the froth depth, air flow rate, impeller speed and pulp density on desulphurization of MT are investigated. 2. Experimental 2.1.

through the pulp. 8.1.3 Froth phase Particles enter the froth phase when a bubble carrying the particles crosses the pulp-froth interface. The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of

Sep 24, 2018· The solids in pulp is the most important parameter that will influence the flotation of minerals. Similar results showing the effect of pulp density on the grade of zinc in the flotation process have been reported by Luo et al. . Other variables did not show a significant influence on the response.

system in which all the other pulp factors were kept constant. The effect of changing the pulp factors on the froth bubble size was investigated by capturing side view images of the froth obtained in a batch flotation cell as each pulp factor was changed.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
