The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener. In the concentrate thickener, the purified slurry is thickened prior to being pumped to a disc filter. Again, the addition of polymer aids in the separation and thickening process.
In mineral processing, the mechanism of thickeners is a critical component for achieving efficient separation, concentration, and recovery of valuable minerals. Thickeners contribute to water ...
The thickening process is a fundamental step in modern mining separation processes Thickening is the separation of suspended particles from a liquid by gravity settling For effective thickener control, six measurements are critical: bed mass inventory, bed level, underflow density and flow, flocculent dosing and overflow clarity
In concentrate thickeners, the feed usually comes from the flotation circuit. The concept of the flotation process is that desired particles attach to air bubbles and are carried to …
process, the conventional thick ener remains as a viable option. As an example of a convention al thickener, Taggart (1945) records the Mt Lyell copper concentrate
The thickening process, although operated successfully in a large range of sites around the world, is poorly understood and predictive design of thickening devices is still empirical. Although predictive models of thickening do exist, the correlation to reality is often poor and there is a desperate need to bring the two together to make ...
The Fluorspar Beneficiation Problem Acid grade fluorspar which is in great demand by the chemical and aluminum industries, must contain at least 97.5% CaF2 with not more than 1.5% SiO2 and 0.5% Fe2O3. Often the Silica is limited to 1.2% with penalties starting at 1.0% SiO2. These limitations on grade and impurities require extremely close …

Thickeners are designed to separate clear and reusable water from concentrate underflow. Conventional feedback control has not been effective in …
What is the Process of Thickening in the Mining Industry? ... Thickeners are commonly used in hydrometallurgical operations to produce concentrate from raw ore and to enhance the solid content of the concentrate mixture (concentrate + treatment water) so that the highly-dense slurry can be supplied successfully and the recycling of …
The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...
The core of thickening process control is to adjust the underflow ore drawing speed in time according to different working conditions. When flocculant is added, it is necessary to adjust the amount of flocculant in time to obtain the best sedimentation velocity, so that the underflow ore discharging speed and ore discharging concentration …
In the flotation process, a high-grade concentrate is produced after the product is separated from the tailings and undergoes thickening and filtration stages. Valuable product- in …
Mining thickeners are the common equipment for dewatering process in mineral processing plants. They are used to concentrate thinner pulp into thicker pulp and separate liquids containing little ...
Operations of the gold concentrate thickening and slurry storage systems are monitored… Gold Concentrate Thickener Inspection | Mining & … Operations of the gold concentrate thickening and slurry storage systems are monitored in the field on inspections that are completed at least once every hour.
Ultimate Guide About Thickener. The quality of thickener will directly affect the result of dewatering operation, and high-quality thickener will increase 20%-30% thickening concentration,then strengthen thickening result. In the current ore dressing process, most mineral processing plant adopt wet separation process, so the …
