Slurry Water Regeneration after Hydraulic Mining

Abstract

Treatment and clarification of coal-day suspensions involve of whole range of technological processes, the efficiency of which depends significantly on the concentration of finely dispersed coal in the water-coal suspension. The behavior of flocculation of coal and clay suspensions with high molecular weight substances making possible to forecast the efficiency of polymer action while controlling the electrokinetic properties and aggregate stability of disperse systems has been studied. Aggregation of fine dispersal particles leads to the acceleration of their sedimentation and intensifies technological processes. The flocculant’s efficiency depends on the molecular weight of a polymer and its structure, the charge value of its functional groups, and also the properties of solid particles’ surfaces, methods of solution preparations etc. These factors must provide strong adsorption during the creation of aggregates and provide a significant influence on the flocculant consumption
