Effects of a cyclonic microbubble flotation column operating parameters on coal process responses
International Journal of Coal Preparation and Utilization, 2023Processing fine and ultrafine coal particles from primary resources is essential for sustainable development. As one of the most recently developed enrichment equipment, cyclonic microbubble flotation columns (FCMC) showed high efficiency in upgrading ...

Intensification of coal slime separation in fluidized bed flotation column: change of turbulence
International Journal of Coal Preparation and Utilization, 2022Flotation cell and flotation column are widely used as the separation equipment for coal slime. In order to obtain better flotation results for different particle sizes, different turbulence intensity of flow field need to be created, but the turbulence ...

Investigation of the induction time and recovery in a flotation column: A kinetic analysis
Separation Science and Technology, 2022The recovery of coal particles in a flotation column was investigated to determine its dependency on the type of frother, particle size, and gas and feed velocities. The kinetics of the cumulative recovery was established.

Bubble Size in a Flotation Column with Oscillatory Air Supply in the Presence of Frothers
Mineral Processing and Extractive Metallurgy Review, 2021Oscillatory air supply has demonstrated advantages over conventional steady air supply in froth flotation with diffused aeration, but the interaction between oscillatory air supply and frother in determining bubble size remained unclear.

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.
