Technologic optimization for separation of scarce coal sludge

, 2009
Qianjiaying coke coal slime is extremely difficult to float. Conventional flotation process leads to a massive waste of high quality coal. In this paper, raw coal slime and rough separation concentrate are grinded to improve separation effect. Coal slime

Aggregation Mechanism of Particles: Effect of Ca2+ and Polyacrylamide on Coagulation and Flocculation of Coal Slime Water Containing Illite

, 2017
Illite is one of the main components in coal slime water and it sometimes makes the water extremely difficult to clarify. In this study, the aggregation mechanism of coal and illite particles was investigated using the extended Derjaguin-Landau-Verwey ...

Preparation of coal slurries deposited in ground settling ponds [PDF]

Acta Montanistica Slovaca, 2005
As a result of the hard coal washing process, considerable quantities of coal slimes are generated. They belong to grain size classes below 1, 0 mm (with the majority of grains below 0,035 mm) and are often sold in order to prepare blends for the power ...

ANALYSIS OF WAYS TO INTENSIFY FLOCCULATION OF FINELY DISPERSED SLIME

, 2017
The object of research is the process of the slime cleaning of the coal preparation plant from suspended solids by flocculation. The process of flocculation is multifactorial and depends on the concentration of the solid phase in the slime, the dispersed
