effect of pulp density in froth flotation

Effect of Pulp Density on Gold Flotation Recovery

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.

Froth Floatation | Factors Affecting Froth Flotation

The main effects of pulp quality score on froth flotation process in metallurgy are as follows: (1) Recovery rate. Within a certain range, when the pulp mass fraction is low, the recovery rate is low; the pulp mass fraction is increased, and the recovery rate is correspondingly increased.

Basic Principles & Variables Affecting Froth Flotation

The effect of slurry density. The percentage of solids in the pulp affects the character of oil necessary in a way similar to that in which it is affected by the degree of pulverization of the ore. A low percentage of solids in a pulp ground to a given degree of fineness means a …

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.

Froth flotationWikipedia

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.

Effect of solids on pulp and froth properties in flotation

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.
