#0183;#32;In coal preparation, thickeners are used to achieve the overall water recovery from the tailings, which are important from both cost and environmental point of views. The process involves sedimentation, the settling of discrete particulates, often enhanced with flocculant to form larger aggregates in a liquid to achieve a higher concentration of solids in the underflow and clarified liquid in
We have paste thickeners for coal preparation plants,Paste thickeners produce thick underflow paste which is stable and will not flow or leach material when exposed to rain This allows coal waste impoundment elimination along with the associated costs and risks of maintaining such waste ponds

The batch settling tests of coal refuse of a coal washing plant that contained 91% particles smaller than 38 #181;m and % coarser than 75 #181;m showed that the optimum feed percent solids that
OVERCOMING THE CHALLENGES OF PASTE THICKENERS IN COAL PREPARATION The use of paste thickeners in coal preparation plants to dewater tailings produces significantly higher concentration of solids than conventional thickeners, which makes disposal easier. However, varying coal tailings types with diverse mineralogical composition,
Coal Preparation Plant Dewatering Dewatering Tailings (reject) Thickeners. Thickeners. Thickeners are used for dewatering slurries of either tailings or product. A thickener is a large circular tank that is used to settle out the solid material from the water in the feed slurry.
Dilute slurry from the primary thickeners is pumped a distance of approximately 3 miles to an area with adequate storage capacity for the expected 25year life of the mine to feed two 59foot diameter paste thickeners at the plants paste disposal facility.

Paste thickeners have been placed downstream of conventional thickeners as a result of recent improvements in paste technology. Paste thickeners produce thick underflow paste which is stable and will not flow or leach material when exposed to rain. This allows coal waste impoundment elimination along with the associated costs and risks of maintaining such waste ponds. Read a case study about
Thickeners. Thickeners or Clarifiers, depending on the application can be used to recover immediately reusable process water, as well as extract fines and other materials. Thickeners are used by mineral and aggregate producers, as well as by environmental contractors in industries such as wastewater management, to separate solids from liquid in a slurry.

Coal tailings are the inevitable byproduct of coal mining and preparation plants, and often are problematic in terms of dewatering and solidliquid separation.
#0183;#32;Abstract The control of paste thickener is important because underflow solids concentration has to be maintained within a certain operating window to maximize water recovery while avoiding operational difficulties, pump bogging. Paste thickener dynamics is complicated due to the interactions between key process variables, uncertainties in operating conditions and large time
All mining concentrators and coal preparation plants have tailings thickeners. These instruments treat the process water by removing suspended solids and then returning the water back to the concentrator or coal prep plant. They then pump the solids to a tailings dam. Reliable bed levels
