Flotation kinetics of coal in the Inflatable Cyclonic Flotation Column

Powder Technology, 2018
This paper mainly investigates the flotation kinetics of coal in the flotation column. The flotation tests were carried out in the Inflatable Cyclonic Flotation Column (ICFC) which consists of two parts, i.e., the inflatable flotation unit and the cyclone flotation zone.

Column Flotation of Coal

2006
Paper is concerning floatability of black coal from Mine Lazy by means of Flotalex, Montanol and PE2 collectors. The goal of the work was verification of floatability of mentioned coal as well as flotation collectors selectivity. The investigation was carried out on class – 0, 5 mm in a column flotation.

Column flotation of talc

International Journal of Mineral Processing, 1989
Abstract Flotation of low grade talc was carried out in a laboratory flotation column with fine air bubbles. Recovery of talc was approximately 83% with a mean residence of 73 s and a whiteness of 84, which was significantly higher than that of a conventional agitation-type flotation cell.

Application of Flotation Column on Flotation of Copper Ore

Advanced Materials Research, 2013
Two flotation columns replacing traditional flotation machine and vertical agitate mill were successfully used on copper production in Yangla mine. With introducing of these advanced machines, chalcopyrite with fine dissemination size could be absolutely liberated. In addition, the technological process was further optimized.

Desulfurization of coal by microbial column flotation

Biotechnology and Bioengineering, 1994
AbstractTwenty‐three strains capable of oxidizing iron were isolated from coal and ore storage sites as well as coal and ore mines, volcanic areas, and hot spring. Four strains were found to have high iron‐oxidizing activity. One strain (T‐4) was selected for this experiment since the strain showed the fastest leaching rate of iron and sulfate from ...

Effect of column height on flotation column performance

Mining, Metallurgy & Exploration, 1988
The question is posed as to why columns typically have a collection zone 10 m high (H) by 1 m in diameter (D). Three geometry dependent factors are considered: degree of mixing, Np; volumetric bias rate, B; and volumetric gas rate, G. Increasing H:D decreased Np and B, which improves performance but decreases G, which causes the column to approach ...

Bubble spargers in column flotation: Adaptation to precipitate flotation

Minerals Engineering, 2000
Abstract The limiting factor for metal-organic precipitate flotation in a column is the level of aggregate stability under the turbulence created by the rising bubbles. The hydrodynamic conditions in a 75 mm diameter pilot column were optimised by using different bubble spargers (Microcel, Flotaire, Imox) and by varying the gas flow rate into the ...

An investigation of the flotation mechanism in the aerosol column flotation machine

Russian Journal of Non-Ferrous Metals, 2009
It is shown that the induction time decreases as the temperature decreases if there is air bubble adhesion to hydrophobic and hydrophilic particles; if there isn’t, the time decreases where hydrophobic particles stick to one another and increases in the case of adhesion of hydrophilic particles.

Beneficiation of fluorspar by column flotation

Mining, Metallurgy & Exploration, 2000
The amenability of column flotation for the beneficiation of fluorspar was investigated, and the overall performance of the column flotation was compared to the performance of the existing conventional flotation cells at the plant. It was established that improved grades and recoveries could be obtained by adopting column technology.
