  • Tailings Mineral Industry Solution - WesTech Engineering, Inc.

    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...
  • How a Thickener Works - Mineral Processing Metallurgy

    Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...
