Tailings Mineral Industry Solution

Paste vs. ConventionalThe advantages of paste thickeners in tailings circuits have been wellestablished 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 nonsettling and nonsegregating 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

Tailings

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
