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

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

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.

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
