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.
Product Applications Tailings Dewatering Fragile flocs, initially settled within the thickener become sheared back to a normal state when pumped from the thickener. The initial 1-4% solids slimes feeding the thickener contained adequate amounts of "free water" to settle within the thickener. The now 25-35% slimes reporting to tailings disposal

More About Tailings & Water Management. Every aggregate or mineral producer who processes rock, crushed stone, sand, coal, limestone, gold, etc. ends up with tailings. Tailings are the unavoidable and undesirable ground rock and process washwater left over from the processing plant after the desired material has been separated.
Spoil Tip
· It features a floor slope that is typically used in high-density thickeners (3:12), which gives it a depth of almost 20m in the centre. Again, the thickener has a diameter of 125m, an installed torque of 10 M lb-ft and rake mechanism of 20 M lb-ft. It uses the forced-dilution P-DUC system, and is designed to process 3,750 tph of tailings.
Tailings. The various reject streams are sent to a tailings thickener. In this unit the solids are allowed to settle and are then pumped to a tailings pond for further settling and water reclamation. The overflow from the tailings thickener is sent to the water reclaim pond and then recycled back into the process.

Kearl Fine Tailings – Thickener Tanks. Fort McMurray, Alberta. Introduction: The Kearl Oil Sands Project is an oil sands mine in the Athabasca Oil Sands region at the Kearl Lake area, about 70 kilometers (43 mi) north of Fort McMurray in Alberta, Canada. The project is being developed in three phases with the first phase completed mid-2013.
Tailings are usually produced at some mineral processing and mine sits. In the mining, the most part of the mines are tailings whereas the extracted minerals are just small part of all fractions. After low-grade ores has been utilized, almost 99% of main materials may finally become tailing. Therefore, tailings contain large part of waste in mining

· The production of consolidated tailings (CT), non-segregating tailings (NST) and proper operation of fines thickeners can be especially finicky. If the fines content is too low, thickener underflow, CT and NST streams will be off-spec and not have the shear stress properties required for eventual reclamation.
· 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.
Design Considerations for a Tailings Disposal System. October 2010 | Features. An effective plan not only considers the thickener, but also evaluates transport distances and the deposition site. By Steve Fiscor, Editor-in-Chief. T he drivers behind paste or high density thickeners are water recovery and cost savings with impoundment construction.

· Concentrate Thickener Operation. In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here we discuss Basic Concentrate Thickener Operation. For the mine to get its concentrate to ...
· A critical stage is the thickening that allows water to be recovered from the tailings, reusing it in upstream operations. However, the performance of the tailings management is usually limited by the rheological properties of the thickened slurries, which impact on the discharge from the underflow of the thickeners, pumping energy costs ...
· These thickeners recover approximately 90 percent of the slurry water by volume. Most mining facilities would then deposit the tailings slurry direct into a tailings pond at about 40 percent to 50 percent solids. But this high-rate primary thickener was inadequate to produce slurry densities required for the desired water reclamation.
Without the measurement of slurry feed density, there is no method by which to optimize the addition of thickening agents. If an insufficient amount of agent is injected, the footprint of the tailings pond will increase, thereby exposing the mining operation to increased risk of contamination.
