Numerical and experimental study of the effect of a froth

Jun 01, 2015· In this work, the effect of a froth baffle on flotation performance is investigated both experimentally and numerically. Flotation experiments with an artificial ore comprised of 80% silica as gangue and 20% limestone as floatable component were carried out to compare the flotation performance of a baffled froth system against an un-baffled froth system.

Froth flotation Wikipedia

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.

Mixing zone: Zone around the impeller of the flotation cell, in the test work of this research located in the cell bottom. Quiescent zone: Laminar flow zone of pulp between the mixing and froth zones of the flotation cell, through which loaded bubbles rise to the top of the cell. Responses: Test results being compared in a factorial design test.
