The article discusses the process of high molecular weight flocculant particles dissolving in water during mechanical stirring. A procedure mixer selection taking into account geometry based on Prandtl’s semi-empirical turbulence model was developed and described. It found that choice optimal rotation speed is related with turbulent frictional stress generated by impeller mixer. results experim...

Sedimentation of ultrafine silica particles that exist in acid leaching pulp and their separation from Pregnant Leach Solution largely determines the efficiency a hydrometallurgical process utilizing copper oxide ore. Thickener on larger scale can allow longer sedimentation, generating low overflow turbidity but high economic input. In this paper, flocculation behavior quartz sulfuric solution ...

Flocculation is a process whereby chemicals (flocculants) stimulate aggregation of colloids and other suspended particles in a suspension to form floc. This is different from precipitation, because prior to flocculation, colloids are suspended in a liquid and not completely dissolved in a solution.1 Flocculation finds usefulness in many fields such as wastewater treatment, downstream processing...

There are still many problems in the stirring dissolution of flocculants: The law flocculants with different molecular weights is not clear, microstructure settling floc particle sizes coal slime to be explored, and how apply flocculant industrialization? To solve these problems, firstly, mechanical tests carried out on anionic polyacrylamide (APAM) explore APAM 3–25 million weights. Results in...
