The thickener or clarifier area must be sufficient to allow the slowest settling particle to reach the bed of compressing solids or bottom of the tank before its associated liquid has reached the overflow. There is a critical concentration in the settling process that the solids will achieve for which the settling rate, and associated upward ...
Water plays a vital role in mineral processing and about 2-3 tons of water is used for the treatment of one ton of ore. The objective of water recovery in thickener is to increase the solids concentration at the underflow to obtain clear water at the overflow.
How a Continuous Thickener Works As a feed stream enters the thickener, the solids settle to the bottom. Clarified liquor overflows to the top and settled solids undeflow is removed from the bottom. The following illustration shows a cross section, schematically illustrating the operation of a continuous thickener.
Mining thickeners are integral to efficient mineral processing and sustainable tailings management. By implementing proper design, operation, and …

Thickeners are important and widely used for mineral processing to make concentrate from ROM (raw ore) . Specifically, thickeners are used to increase the solid content of concentrate slurry ...
The simplest use of a thickener in a metal-mining operation is to get water out of a pulp; for example, in a desert country where water is too valuable to be thrown away with the tailings. There you have a …
The thickener is a tailing or concentrates dewatering equipment commonly used in the mining industry, which is mainly used to separate the water to achieve the purpose of solid-liquid separation. ... and waste residues in metallurgy, chemical, coal, non-metallic mineral processing, environmental protection, and other industries.
The dense Thickener solids are raked to the thickener's underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed, size distribution of solids being settled, or other process factors but as a general rule, range from 35-50% solids by weight.
Thickener Waste Management in Mineral Processing To Prevent Environmental Pollution Marzieh Hosseini Nasab1 1Department of Mining Engineering 1 University of Sistan and Baluchestan 1 Zahedan, Iran Abstract— Water plays a vital role in mineral processing and about 2-3 tons of water is used for the treatment of one ton of ore.
In the current ore dressing process, most mineral processing plant adopt wet separation process, so the concentrate has very high water content, which can't be smelted directly. ... After several improvements of Xinhai, this thickener is equipped with larger processing capacity, lower overflow turbidity and higher discharging concentration. It ...
Over the years, nomenclature has been adopted that is specific to thickener functions in the mineral processing industries. The solid-liquid mixture that is to be separated by sedimentation is known as the feed. The sedimented material having a solids content higher than that of the feed is the underflow. The clarified liquid from which solids ...
Tailings, the by-products of mineral processing, often contain fine particles and water. Thickeners are extensively used to dewater and thicken the tailings, reducing their volume and facilitating proper disposal or storage. ... It is recommended to involve experienced engineers, process experts, or thickener manufacturers during the design ...
Xinhai provides mineral processing technology, equipment manufacture and one-stop service for mineral processing plant, which solve many problems for mine investors. ... High-efficiency Thickener. Increase the efficient settlement area volume; Add the feed pipe under the liquid level, deaerating tank, inner over , and zigzag overflow ; ...
thickener tank EIMCO KCP Thickener tanks are constructed either from bolted / steel welded or concrete. Most of the chemical process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tank's floor for leakages and bring the underflow slurry pumps nearer to the outlet of the ...
