Thickener - Mineral Processing

13/07/2020  To start with, mineral thickener works on the principle of Gravity sedimentation and the most common construction of a thickener would be of iron or steel. 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 The clarified liquid overflows a trough, while the solids which settle at the bottom of the tank are withdrawn as a thickened pulp

13/07/2016  The Dorr washing thickener is of the multiple-tray type and is, in effect, a complete countercurrent decantation plant in a single compact unit. It is adapted to the needs of the small chemical and metallurgical plants where a relatively small tonnage of finely divided solids must be washed free from a solution in a minimum space. Four to five stages of washing are usually provided in separate

Combined with a flow meter, the mass flow can be calculated, giving real-time insights about the efficiency of the thickener operation. In mineral processing operations, water is very important and therefore water recovery plants have an important position. According to CRC Care 2013, every year more than 10 billion tonnes of tailings are produced by mining activity. Thickeners can be used as ...

Mine Thickeners, Thickener Mineral Processing,

In the current ore dressing process, most mineral processing plant adopt wet separation process, so the concentrate has very high water content, which can't be smelted directly. As the first step of dewatering operation, thickening operation occupies 9% influences on the whole beneficiation process, and 35% effects on the whole dewatering operation. The quality of thickening equipment will ...

High Rate Thickening is a process whereby mineral particles are flocculated, thoroughly mixed within a feedwell and then injected uniformly into a hindered settling zone in the thickener with largely radial motion. A pre formed hindered settling zone allows horizontal distribution of incoming feed into the settling bed which, at the point of injection, is in a fluidised state. The radial ...
