Comprehensive Guide to Mining Thickeners | Mining Pedia
1. Definition and Purpose. Mining thickeners, also known as clarifiers or settlers, are large sedimentation tanks used in mineral processing operations. They are designed to separate solids from liquids, allowing for the efficient concentration of solids and the recovery of valuable minerals.
Beginners guide to thickeners
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 ...

High Density thickeners are generally designed for the range of 30–100 Pa, and Deep Cone, Deep Bed or Paste thickeners for over 100 Pa. It should be noted that these designs cover a wide range. ... A typical yield stress vs. solids concentration curve for iron ore tailings is shown in Fig. ...
High Rate Thickeners
Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned …

99.6%. Under our assumptions, a three-stage CCD circuit using paste thickeners outperforms a four-stage CCD with high-rate thickeners (97.6% vs 96.2%). The process choice is clear, unless high volumes of wash water are justifiable; which of course depends greatly on the values contained in the pregnant liquor.

Paste Thickeners
Typical paste thickeners drives have 8-10 times the torque compared with the same diameter high rate thickener. In addition, paste thickeners need to have much longer mud retention times in order to thicken to higher densities. That makes the tanks much deeper, again adding cost, but also an area where it's possible to skimp and under-design.
