High Density Thickener

Amstar’s high density 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 high density Thickener results in lower pumping costs — an important factor for deposition areas far from the plant.
