Mine Water Management and Recycling: The Importance of Thickener

A thickener is a device that filters liquids from solids. Thickeners were first used in the mining business in 1905. ... Thickeners are commonly used in hydrometallurgical operations to produce concentrate from raw ore and to enhance the solid content of the concentrate mixture (concentrate + treatment water) so that the highly-dense slurry can ...

General guide to concentrate filtration

The filtration area, such as filters, mainly works with the underflow solids from the thickener. The thickened solids can be as high as 68-70% solids by weight, averaging 63-65% solids feed. Figure 1 below shows the process flowsheet of the concentrator plant, and how the process before the dewatering is done, as well as after.

Solid – Liquid Separation – Thickening

In general, 75–80 % of the water can be separated and removed by thickeners. For further water removal, filters are used where in excess of 90% of the water can be removed. The thickener operation can be a batch or continuous process, with either co-current or counter-current flow of underflow and overflow slurries.
