Sedimentation and electro-osmotic dewatering of coal-washery slimes

Fuel, 1981
Abstract Dewatering of three samples of fine-tailings from two Australian coal washeries, where the clay content of the tailings is predominantly either the swelling or the non-swelling type, is examined on the laboratory scale. Thixotropic slurries of ≈ 55 wt% solids are achieved by sedimentation of the crude or prethickened tailings.

Floc-flotation of ultrafine coal slimes achieved by flotation column

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2017
ABSTRACTIn 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.

IMPROVEMENT OF THE EFFICIENCY OF FINE COAL SLIMES FLOTATION

2016
The problems of selective flotation of fine slimes have been analyzed. Different technical solutions aimed at the improvement of the efficiency of flotation of coal containing fine slimes have been considered. As a criterion of the efficiency of separation results in flotation the index of maximum flotation ability has been suggested, which is ...
