The effect of clay slimes on coal flotation, part II: The role of water quality

International Journal of Mineral Processing, 1986
Abstract Suspended clay solids, ions, pH and humic acid are shown to have a significant influence on coal flotation. Coal flotation is greater in tap than in distilled water. This is believed due to instability and thinning of the hydrated layer at the surface of the coal particle when ions are present.

Dynamic floc characteristics of flocculated coal slime water under different agent conditions using particle vision and measurement

Water Environment Research, 2019
AbstractTo determine the effect of different agents on the dynamic characteristics of floc structures, ferric chloride (FC) and anionic polyacrylamide (APAM) were dosed as coagulant and flocculant, respectively, to flocculate the coal slime water. Particle vision and measurement (PVM) was employed to monitor the flocculation process in situ.
