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.

Coal flotation to satisfy coal quality

Filtration + Separation, 2017
During the coal flotation process, high ash coal fines are carried into foam, although process optimization can reduce ash content. This paper suggests an alternative method for coal flotation which has a significant effect on quality, coal production processes and plant design.

Coal Reverse Flotation. Part II. Batch Flotation Tests

Coal Preparation, 2003
Coal reverse flotation, a process in which coal mineral matter is floated instead of the organic matter, was studied through a series of batch flotation tests on artificial coal/silica mixtures using two coals varying in rank. Dodecyltrimethyl ammonium bromide (DTAB) was utilized as a mineral matter collector, while humic acids (sodium salt) were added

Flotation characteristics of oxidized coal

Fuel and Energy Abstracts, 1995
Abstract The floatability of oxidized coal was investigated by means of electrokinetic studies, contact angle measurements and flotation tests. Electrokinetic measurements showed that the zeta potential of unoxidized and oxidized coal samples depends on pH.

High-Efficiency Nanobubble Coal Flotation

International Journal of Coal Preparation and Utilization, 2013
The high efficiency of a froth flotation process is limited to a narrow particle size range. Nanobubbles integrated into a specially designed flotation column expanded the particle size range for effective froth flotation as a result of increased probabilities of particle-bubble collision and attachment and reduced probability of detachment.
