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.
