Paste thickening optimizes tailings disposal and water

By Jim McMahon Mine tailings disposal and its impact on water usage is an important concern for any mining company The challenge today whether extracting aluminum zinc gold or iron ore is how to dispose of tailings material such that it is contained and stable while maximizing water reuse and minimizing surface footprint

Sludge Thickening Sludge Thickening Process Thickening

Sludge thickening is a a low investment process used commonly in wastewater treatment plants to remove as much water as possible from the liquid sludge The method involves increasing the concentration of the solids in the sludge so that they can be easily dewatered

Stoke s Law applies only in streamline flow and strictly only to spherical particles In the case of spheres the criterion for streamline flow is that Re = 2 and many practical cases occur in the region of streamline flow or at least where streamline flow is a reasonable approximation

SEDIMENTATION

A particle or droplet will settle in a fluid if its density is greater than that of the fluid in which it is suspended The laminar settling velocity of particles whose concentration is very low that is when the flow of fluid around a particle does not affect the flow around neighboring particles can be calculated from Stokes Law

New Associative Thickeners and Their Use In

The structure built up between the PUR associative thickener and the emulsion particles is relatively resistant to mechanical effects leading to a virtually Newtonian flow behavior Figure 5 demonstrates the rheology profile of a PVC dispersion paint thickened with a PUR associative thickener SER AD FX 1010 and an HEC thickener

Shear thickening in a model colloidal suspension The

We study the rheology of model colloidal suspensions using molecular dynamics simulations We relate the onset of shear thickening to the transition from a low viscosity regime in which the solvent facilitates the flow of colloids to a high viscosity regime associated with jamming of the colloids and the formation of chains of colloids In the low viscosity regime the colloidal particles

Investigating the Impact of Particle Characteristics on

Elongated particles randomly orient at low shear and occupy larger volumes but at high shear will tend to orient along the direction of flow to result in more efficient packing Consequently suspensions with elongated particles also shear thin but in a far more pronounced manner than those consisting of spherical particles In terms of the
