Introduction. Thickened tailings, as the name suggests, involves the mechanical process of dewatering low solids concentrated slurry (Fourie 2003). This is normally achieved by using compression (or high rate) thickeners or a combination of thickeners and filter presses. High Density Thickened Tailings (HDTT) are defined as tailings that have ...

The standard feed well for conventional thickeners is designed for a maximum nominal flow velocity of 1.5 m/min. High turbidity caused by the depth of the feed well. When overflow clarity is important or the solids gravity is close to the liquid specific gravity, deep feed wells of large diameter are used.

Jun 16, 2017· Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...
