Why high rate thickeners are now preferred by the gold

Typically, the capital cost of a conventional thickener (eg, 30m dia unit for a 500,OOOtpa gold treatment plant) would increase the cost of the treatment plant by 10 15%; the use of a high rate thickener (10m dia unit for 500,OOOtpa) would result in a 3 4% increase only in the plant cost and achieve the same water and cyanide recovery.


Visual Encyclopedia of Chemical Engineering

Thickeners and clarifiers use slowly rotating rake arms to separate solid particulate. A liquid feed with suspended solids is fed into a tank with a diameter of 5 to 500 feet. As the particles settle, angled rake arms move the concentrated slurry toward the center of the tank, where it is removed.


Paste Thickeners Jacol

The underflow of high rate thickeners is quot;slurry,quot; which has relatively no or only minor yield stress. Conversely, WesTech compared to conventional or high rate thickeners. A smaller footprint, increased water recovery, and paste/thickened tailing percentage points higher than underflow from a high rate thickener.


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.


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.
