    Tailings Paste ThickeningPaste vs. ConventionalWater RecoveryStackingExtend Pond LifeThe advantages of paste thickeners in tailings circuits have been well-established for most minerals. The type of paste thickener underflow generally used for surface stacking of tailings is called “thickened tailings.” Thickened tailings are a suspension of solids which are relatively non-settling and non-segregating and which have a higher concentration and viscosity than that of conventional tailings.Common applications include a thickener with underflow pumps that are typically centrifuga
