WesTech DeepBedTM paste thickeners (sometimes referred to generically as deep cone type thickeners) are characterised by a height to diameter ratio between one and two, a bottom cone angle of 15-45o, and a bridge mounted drive. Diameters are limited to about 24 m for this type of paste thickener. The mud bed height is
FL uses the terms High Density and Deep Cone, Westech uses the terms High Density and Deep Bed, Delkor uses High Density and Paste, and Outotec uses the terms High ... Australia 2 Development of thickening technology Thickeners were invented in the early 1900s though batch settling tanks go back much further. John Dorr
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 …

In underground mining, the WesTech Deep Bed™ paste thickener is an emerging option to the conventional solution of high-rate thickener/vacuum filter for paste backfill …
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.
plant in south-eastern China, their water treatment plant precipitate is dewatered in a WesTech Deep BedTM paste thickener equipped with an EvenfloTM two stage feedwell. The mixing zone in the feedwell and the clarified water are seen in the Figure 6. These photos were taken at design flow rate.
That's particularly true when it comes to the thickener you use. Higher underflow pulp concentrations are critical when it comes to efficiency and water recovery. Uniformity in underflow slurry consistency is also key. The Deep Cone Thickener maximises pulp concentration while also producing non-segregating underflow slurry with a paste ...
In underground mining, the WesTech Deep Bed™ paste thickener is an emerging option to the conventional solution of high-rate thickener/vacuum filter for paste backfill applications. There can be a number of factors that make paste thickening an attractive alternative. ... and copper. It is mined mostly in Canada, the former USSR, Australia ...
These filters normally have a single media consisting of a course media bed. The deep bed filters are used to remove the fine particulates suspended in the water and to coalesce the remaining oil. The treated water from the deep bed filter is sent to a cooling tower prior to being reused in the continuous caster process. Thickener and Filter Press
In 2015, SBPIL replaced their high rate tailings thickener with a 14 meter (46 foot) WesTech Deep Bed™ paste thickener. Deposition is in an existing 3.6 hectare (9 acre) tailings pond, accomplished by pumping paste to three towers located in different zones of the impoundment as illustrated in Figure 1 (small version below; full-size at the ...
The WesTech Deep Bed Paste thickener produces non-settling and non-segregating underflow with the maximum rheology (density) possible. WesTech is a leader in paste technology with diverse application experience and …
WesTech is supplying the Deep Bed™ paste thickeners required to produce the target feed density for four of the acid plants. WesTech is also supplying the pumps, instrumentation, and surge holding tanks. WesTech/Paste Thick™ recommended and designed process control to insure a tight underflow density for the acid plant.
The WesTech Deep Bed Paste Thickener can thicken a tailings stream to non-settling paste at solids concentrations approaching that of a filter cake. Design characteristics of the Deep Bed™ result in maximum water …

An 18m diameter 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 …
The patented WesTech EvenfloTM is a design that uses an inner feedwell that communicates with an outer feedwell through radially ports that direct the feed flow …
WesTech's HiDensity™ Paste Thickener produces non-settling thickened tailings with lower viscosities and underflow concentrations than what is produced in the Deep Bed™ Paste Thickener. The HiDensity Thickener also has a lower height-to-diameter ratio, which allows for on-the-ground construction and much larger ...
Jerold Johnson of WesTech Engineering recounts the birth of the MudMax, a first-of-its-kind tool for accurate bed-level measurement in paste thickeners.
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
paste thickener was significantly lower than the high usage of belt press filters. PasteThick™/WesTech recommended and provided a system layout to place the paste thickener near the impoundment site to reduce the cost of transporting the paste thickener underflow. A 15m-diameter WesTech Deep Bed™ paste thickener was installed above …
WesTech Deep Bed paste thickener at phosphoric acid plant. Clarification. Clarifiers remove fine gypsum from the phosphoric acid product to ensure a pure liquid for later production steps. The primary goal of the clarifier is to evenly distribute the feed in the tank so the liquid-solids separation takes place across the entire tank.

percentage points higher than underflow from a high-rate thickener. The WesTech Deep BedTM paste thickener is the latest advancement in the evolution of this style of thickener. To be able to consistently dewater the tailings slurry to a non-settling and non-segregating suspension, WesTech Deep BedTM paste thickener design includes:
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.
