thickened tailings thickener sludge

High density slurry and paste tailings, transport

The successful design of a thickened or paste tailings system requires that the system is designed to accommodate the effect of the high density slurry on pumps, pipelines and the overall system operation.

Tailingsfo Surface Paste Disposal

Paste tailings are defined as tailings that have been significantly dewatered to a point where they do not have a critical flow velocity when pumped, do not segregate as they deposit and produce minimal (if any) bleed water when discharged from a pipe (figure 1).

Solid Liquid Separation Thickening ScienceDirect

Alternately, the thickened slurry is swept towards a trench at the bottom of the tank. Usually, a scraper is installed for smooth delivery of sludge from the discharging cone or trough. A slush or centrifugal pump subsequently removes the sludge. The thickener tanks are usually fabricated using steel sheets.

Case study project start up for thickened graphite

Tailings coming from the thickener underflow pumps are expected to be discharged as 50% solids/50% water slurry by weight. The tailings feed will be flocculated and densified in the thickener to minimise the volume of water that will be sent with the tailings to the TSF and to achieve the desired tailings



Tailings Decanter centrifuges flottweg

the extraction process, the tailings are in a thick semi fluid sludge state, often with trace elements of the extraction reagents. Historically, these tailings are deposited in thickener. The thickener is a conical bottom vessel equipped with scraper paddles that move thickened material to a discharge

Tailings Mineral Industry Solution WesTech

Paste thickeners thicken tailings to higher underflow solids concentrations than conventional and high rate thickeners. For example, a tailings stream in an iron ore application could be thickened to 4550% solids Newtonian slurry in

Waste sludge treatment in the CPI

vices are available from thickener manufacturers. Table I11 lists industrial performance data for several sludge thickening operations. Dewatering The purpose of dewatering is to remove sufficient liquid from the thickened sludge to produce a cake that has optimal handling properties and solids content for subsequent processing or disposal.

A stratified enhancement pattern in a thickened segment of bowel wall is used to exclude malignant conditions and is, therefore, a very important criterion to use to establish a correct diagnosis.

Belt thickener / for sludge treatment HiDensity

The HiDensity Paste Thickener offers the advantages of paste and thickened tailings for very large tonnages. Water savings and tailings deposition can be accomplished with fewer tanks and at a lower capital cost than with the equivalent number of Deep Bed paste thickeners.

Tailings Central Thickened Discharge; challenges SRK Consulting. Aug 2, 2016 are large unforeseen variations in thickener performance and limited proposes key areas to focus on to mitigate against and lessen the impact of . cone thickeners and flotation tailings would be thickened in a high rate.

Thixotropic behaviour of thickened sewage sludge

Apr 23, 20140183;32;The aim of the work is a description of the rheological behaviour of thickened sewage sludge. The sample of thickened sludge was collected from the wastewater treatment plant, where pressure flotation unit is used for a process of thickening.

Copper Tailings Elmhurst College

(The El Paso smelter is on stand by status). Water is recovered from the tailings in another thickener. The thickened tailings flow by gravity in large pipes to tailings ponds, where the solid material settles out and additional water is recovered and pumped back to the mill.


Location of the thickener in a wastewater treatment plant is important. If sludge is to be digested, thickening a blend of primary and waste activated sludge is a good practice.

In Table I of the July article, quot;improve Clarifier and Thickener Design and Operation,quot; by Joel Christian (pp. 50 56), the titles Vi and TSS are reversed. The first TSS is 3.1 and the first Vi is 6.045. In the overloaded case on p. 55, the underflow c oncentration should be 240 kg/m 3, not 140. Also, the dashed line in Figure 9 is not used in

Paste thickening optimizes tailings disposal and water

But this high rate primary thickener was inadequate to produce slurry densities required for the desired water reclamation. WesTechs solution used paste thickening technology to facilitate a second stage tailings thickening process.

Sludge Thickening Sewage Treatment Reverse

Sludge is usually pumped continuously from the settling tank to the thickener which has a low overflow rate so that the excess water overflows and the sludge solids concentrate in the bottom. A blanket of sludge is maintained by controlled removal which may be continuous at a low rate.

reduction is different. Generally thickeners concentrate sludge at lower than 15% concentration, the dewatering units concentrate the sludge to higher than 15% concentration [3]. Thickened sludge still behaves as a liquid and can be pumped. However, the dewatered sludge generally behaves as a solid and can be trucked in
