In the present study, the thickening process of tailings slurry in a gravity thickener is modelled using Computational Fluid Dynamics (CFD), with a focus on the effects of particle size and feed velocity. A Two-Fluid Model (TFM) is employed to describe the particle-fluid and particle-particle interactions while turbulence is described by the ω …
A wide variety of thickener tank designs are currently being used. Most applications require that the underflow pump is located with as short a pump suction as practically possible, which means either that the tank has to be elevated or that there is a tunnel under the thickener to allow access to the centre of the thickener.

If the same event occurs in the thickener tank, the could carry valuable materials into the overflow. When these valuable materials aren't recovered, this will lead to a lower overall recovery of concentrator metal at the processing plant. This event can also lead to extra reagent costs, damage to pumps and valves and costs for cleaning ...
High-Rate Thickeners are used to achieve moderate underflow density and good overflow clarity with low chemical dosage. They also offer high liquid recovery. High-Rate Thickeners feature a tank with …
Introduction The thickener is applicable to the dehydration treatment of concentrate and tailings in concentrators, and is widely used in the concentration and dehydration of slime, wastewater and waste residue in metallurgy, mining, coal, chemical industry, building materials, environmental protection and other departments.
Important independent variables in thickener operation include: (i) underflow discharge rate, (ii) feed solids rate, and (iii) flocculant dosage to the feed tailings stream (Cacciuttolo and Holgado, 2016). The majority of mineral tailing suspensions exhibit an exponential increase in yield stress with increasing solids concentration.
the slope of the tank floor. The thickener system demonstrated . great efficiency in consistently achieving pulp dilution to a relatively low solids concentration in the thickener feedwell, which improved the flocculation and settling/sedimentation rate. We later constructed a second of these thickener systems, due to the customer's plant ...

Pressure transmitter, Rake Torque, Sonar Transmitter. Tailings Thickeners are extremely important, to the efficient operation of Concentrators, Coal Preparation Plants, and other mining and mineral industry applications. Tailings Thickeners are used to settle out suspended solids and return the clear water to the process.
This is the case for most older thickeners, where large tank diameters (and hence low liquor rise rates) create less demand on settling flux. Solids dilution is a much greater priority in modern paste thickeners, for which it is hard to imagine low settling flux conditions being applicable. 2. Maximising thickener underflow solids concentrations
Because of high percentage of solids in the mud, producers can greatly reduce the size of their settling ponds or tailings storage facilities. Paste Thickeners feature tanks with …

Thickener operations Thickener operations work to recover clear water and to generate thickened tailings. In the thickener, the solids separate from the water by means of decantation, and they descend to the bottom of the tank. Consequently, the water becomes clearer at the top of the tank, creating separation layers all the way to the bottom.
The Cogede high rate thickener or thickener plants can be installed on tank made in carbon steel or on tank made in concrete.

The continuous thickener consists of a cylindrical tank. Pulp is fed into the centre of the tank via a feed-well placed up to 1 m below the surface of the suspension. The clarified liquid overflows a trough, while the solids which settle at the bottom of the tank are withdrawn as a thickened pulp from an outlet at the centre.
