Abstract A compact (75 cm ht × 7 cm dia.) semi-batch type flotation column was developed for use as a convenient testing and research apparatus especially in laboratories that do not have sufficient headroom for a full-size experimental column installation.

Microcel™ Flotation Column Modelling
Coal Preparation, 1998A full-scale Microcel™ flotation column was trialled at the BHP Coal Peak Downs Mine and Saraji Mine coal preparation plants for the treatment of 0.5 mm × 0 (−500 μm) coal. By using deep froths and counter-current froth washing, the Microcel™ columns have been demonstrated to achieve substantially lower product ash compared to conventional flotation ...

Troubleshooting industrial flotation columns
Minerals Engineering, 1995Abstract Since the early 1980s flotation columns have been progressively incorporated in milling operations all over the world. Improvements in final concentrate grade, using single cleaning stages, have been in most cases the reason for using this new technology.

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.

Effect of frother addition mode on gas dispersion and coal flotation in a downflow flotation column
, 2020The traditional addition mode of frother as liquid and a novel mode as vapor were comparatively studied in presences of methyl isobutyl carbinol (MIBC) and sec-Octyl alcohol (2-octanol).

Optimization of gas parameters in a three-phase fluidized bed flotation column
, 2020The gas parameters, including gas holdup, bubble diameter and bubble specific surface area flux, of a three-phase fluidized bed flotation column (TFC) have been systematically studied.

Selectivity in phosphate column flotation
Minerals Engineering, 2007Abstract The objective of this work was the study of the selectivity of apatite flotation in a column by means of kinetic analysis. The recovery and apatite content in the concentrate were correlated to the collector dosage, depressant dosage and air flow rate.
