Filtration and thickening are areas of mineral recovery technology that are often overlooked. Nonetheless, they represent an important component of the entire process, since without dewatering, it would be hard to produce concentrates to transport specifications while water recycling from tailings streams is becoming increasingly important as energy costs for pumping steadily increase.

An 18m diameter WesTech Deep Bed™ Paste thickener was installed. The image below shows the pond being processed (dredging right of center near dam) and the delta formed by subaqueous deposited paste tailing (center bottom). The process plant is in the center top and the paste thickener located toward the other end of the pond (left of center).
WesTech - Deep Bed™ Paste Thickener The original concept of the deep cone thickener was developed in the 1960's using a steep angled cone and thickener bed to increase underflow density. Over the years, this thickening technology has evolved to produce a non-settling solids suspension with underflow concentrations much higher than what is ...

A paste thickener underflow is non-Newtonian (Boger 2003). To understand these properties, so different from that of water and settling slurry, examine the suspension on an individual particle level (Fig. 1; WesTech Deep Bed™ Paste thickener manual 2019). The tailings stream leaving the process plant is a suspension of some coarser particles ...

HiDensity™ Vue d'ensemble de l'épaississant Paste Thickener : L'épaississant en pâte de WesTech HiDensity™ produit des résidus épaissis non décantés avec des viscosités et des concentrations sous l'eau inférieures à celles produites dans l'épaississant en pâte de WesTech Bed™ Paste Thickener.
A compromise option of using a rakeless (ULT) design can be considered. In this case, the cost and complexity of a mechanical drive is traded off for a deep mud bed and steeper 60 degree floor slope picture . The ULT design will not achieve the same underflow density as the paste thickener with rake and pickets, but it can be more economical.

WesTech Deep Bed Paste Thickener was installed. A dam raise was needed at the end of year one after the surface stack was begun. Over five years of operation, the dam elevation increased over 20 meters. Comparing photos 8 and 9, the white control room building can be used as an elevation reference. At this point, the
The disclosed apparatus may include a mounting structure. A first arm may be secured to the mounting structure and extend from the mounting structure. A load cell may be mechanically coupled to the first arm to detect a first load applied to the first arm by relative movement between the first load cell and a viscous material in which the first arm may be submerged or at least partially disposed.
Paste thickener technology entered the Indian iron market in 2015 when the Shri Bajrang Power and Ispat Ltd (SBP&IL) plant installed a 14 m diameter WesTech Deep Bed TM thickener. This site provides a good study for paste thickener use to address some of the iron slimes and TSF issues. This site has a small TSF footprint.

A deep cone, or deep bed, thickener produces paste. Both high density and deep cone thickeners depend on retention time rather than area. Yield stress is the dividing line between paste and thickened tailings, and deep cone thickeners produce a yield stress of 120 to 150 Pascals (Pa) and greater.
