WesTech’s HiDensity™ Paste Thickener produces non-settling thickened tailings with lower viscosities and underflow concentrations than what is produced in the Deep Bed™ Paste Thickener. The HiDensity™ Thickener also has a lower height-to-diameter ratio, which allows for on-the-ground construction and much larger diameters.
The HiDensity Thickener offers the advantages of paste and thickened tailings for very large tonnages. Water savings and tailings deposition can be accomplished with fewer tanks and at a lower capital cost than with the equivalent number of Deep Bed paste thickeners.
Reduced viscosity associated with the underflow concentrations of the HiDensity Thickener results in lower pumping costs — an important factor for deposition areas far from the plant.
