Control of a High Rate Thickener on Gold Plant Tailings
The use of High Rate Thickeners has gained wide acceptance in the mineral treatment industries. The design of these units is characterized by an efficient deaeration and flocculation chamber, and introduction of the flocculated feed solids into a preformed floc bed zone. By these means the settling process is accelerated and consequently High

Another important consideration is the overflow rate. Overflow rates between 380 and 760 gpd/sq ft are typically used for primary solids. Overflow rates in the 100 to 200 gpd/sq ft range are used for thickening secondary solids. A high overflow rate can result in excessive solids carry -- over. A low overflow rate (corresponding to high thickener

High Rate Thickeners - Solid Liquid Separation
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 far

Not only are they tasked with providing high-quality raw materials for consumption, but they must also meet increasing demands for environmentally conscious practices. Thickeners and clarifiers, when properly optimised for performance and operating cost, offer some of the most cost-effective technologies available to meet both of these goals.

Feedwell is the heart of a thickener - University of Western Australia
AMIRA conducted a CFD study of this two stage feedwell, similar to that reported in their P266 project. The results are shown in Figure 5. The design tested was for a 14.5 m feedwell in a 100 m high rate thickener. The inner feedwell diameter is about 8.5 m. The flow rate was varied from 9,000 to 17,000 m3/h.

It should also be understood that if the solids flux rate changes (i.e. an in-creased feed rate and underflow withdrawal rate for a given cross-sectional area), the liquid rise rate also changes, resulting in a different bed dynamic and a varia-tion in the settled density. Figure 2: Bench-scale 94 mm high rate thickener.

McLanahan High-Density Thickeners
High-Density Thickeners separate liquids from solids using gravity settling. A key requirement is to contact the solids with added chemicals under the right shear conditions for building large floccules. The efficiency of flocculation contributes to an enhanced settling rate. Once settled in the bottom of the tank, the deep mud bed is further ...

Constrained model predictive control of an industrial high-rate ...
This results in high underflow slurry density fluctuations and high solids content in the overflow [3]. Manual operation is not usually enough to satisfy the desired efficiency of the separation. Various approaches for controlling thickeners have been documented in the literature, and among them is the use of expert systems [4], [5], [6], [7].
