Desulfurization of coal by microbial column flotation
Biotechnology and Bioengineering, 1994AbstractTwenty‐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 ...

Flotation kinetics of coal in the Inflatable Cyclonic Flotation Column
Powder Technology, 2018Abstract 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.

Floc-flotation of ultrafine coal slimes achieved by flotation column
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2017ABSTRACTIn this investigation, the floc-flotation performance of ultrafine coal slimes in the large-scale 5500 × 7000 mm cyclonic-static micro-bubble flotation column (FCSMC) was explored. A laser particle size analyzer was used to indicate the changes in particle size distribution with or without adding a flocculant.

Column flotation of Coal Slurries
2006Paper is concerning floatability of coal slurries by means of different flotation collectors. The goal of the work was verification of floatability of coal slurries as well as flotation collectors selectivity. The investigation was carried out in a column flotation.

Column flotation of bituminous coal
2008The objective of the paper was a comparison of classical and column flotation on samples of black-coal slurries from selected localities of okr and poland. Namely they are dukla mine, darkov mine, csm mine, csa mine, doubrava mine and kleofas mine. The acquired results imply that the methods of classical and column flotation are suitable for flotation ...

Improving controllability on flotation columns
2000Abstract Flotation columns are common devices in cleaning circuits in the mineral processing industry. The operation and control of these columns often have the final responsibility for the quality of the concentrate grade and, to a less extent, for the recovery of the cleaning circuit.
