thickeners for tailings

Tailingsfo Thickened Tailings Storage A discussion

Thickened tailings, as the name suggests, involves the mechanical process of dewatering low solids concentrated slurry (Fourie 2003). This is normally achieved by using compression (or high rate) thickeners or a combination of thickeners and filter presses. High Density Thickened Tailings (HDTT) are defined as tailings that have been

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 conventional or high rate thickeners.

How a Thickener Works Mineral Processing Metallurgy

Dorr thickeners are used in the metallurgical field to thicken prior to agitation and filtration, in the countercurrent washing of cyanide slime, for thickening ahead of flotation, for thickening concentrates, and for dewatering tailing to recover the water for reuse in the mill.

Paste thickening optimizes tailings disposal and water

Mine tailings disposal, and its impact on water usage, is an important concern for any mining company. The challenge today, whether extracting aluminum, zinc, gold or iron ore, is how to dispose of tailings material such that it is contained and stable, while maximizing water reuse and minimizing


Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without

Tailing Disposal Methods and Tailings Dam Construction Design

Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.

Conventional Thickeners Solid Liquid Separation

Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away.

density enable more acidic tailings return liquor to be used back in the plant. Modelling of stability, seepage, groundwater and geochemical analyses have been carried out using data obtained from field and laboratory investigations carried out for this and earlier studies.

(also called quot;thickened tailingsquot;) offers unique advantages Increased water recovery Smaller tailings disposal volumes Maximum product recovery from a thickener Paste/thickened tailings is a term for a non Newtonian suspension of solids which are relatively non settling and non segregating.

Mill tailings management high density thickened slurries

Thickener designs have evolved to allow for compression of the settled slurry in the thickener by deepening and steepening thickener cones, and rake designs that promote the release of water by shearing flocc have improved significantly.

Design Considerations for a Tailings Disposal System E MJ

The tailings stream was first processed by a high rate thickener to recover a large portion of the water near the plant. The underflow then traveled 4.5 km to a deep bed paste thickener, located adjacent to small valley where the tailings would be surface stacked.

Tailingsfo Surface Paste Disposal

Additives such as flocculants and coagulants are usually added to the tailings feed or the thickener to dewater the tailings to higher densities. The types of additives used reflect how the paste behaves when pumped and how the tailings will flow once at the storage facility (Fourie 2003).
