Is column flotation still relevant? AusIMM Bulletin

Is column flotation still relevant? Since 1961, column flotation has gone through three distinct rises and falls in popularity. These fluctuations have largely been driven by commodity prices. Within these primary waves, there are secondary fluctuations in popularity driven by the rise and fall of individual flotation column manufacturers, the

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone 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.

Drift Flux Modelling for a Two‐Phase System in a Flotation

Using different two‐phase systems, a laboratory flotation column was operated over a wide range of bubble size from 250 to 1100 µm. The drift flux analysis for the tests was used to obtain a new correlation to relate the characteristic exponent m in the drift flux equation j gf = U t α g (1 — α g) m, to bubble Reynolds number, where j gf is the drift flux, U t is the terminal velocity

Height The original flotation columns marketed by Column Flotation Co. of Canada were 40--45 ft high [5] and this became, in essence, the standard. One advantage was that height was then not a factor and scale up could focus on the number and diameter of the columns required. The need for this height has always been in question, however. Some justification was given from analysis of mixing by

New concept in flotation column design SpringerLink

A form of column flotation cell is described in which the contact between the feed and the air stream is made in a mixing device at the top of a vertical downcomer. The air-liquid mixture flows downward to discharge into a shallow pool of pulp in the bottom of a short cylindrical column. The bubbles disengage and rise to the top of the column

A Study of Flotation Column Performance for the Recovery

As an alternative to agitated cells, bubble columns-used in stone engineering practice as stone reactors-were proposed for the treat- ment of fine particle systems. Flotation columns, as they came to be known, were “invented” back in the 1960s (1,2) in Canada, and it seems that they were operating in China, too, by 1961 (3). The

Froth Flotation Process Mineral Processing & Metallurgy

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
