The thickener could be used to recover immediately reusable water back to mineral processing plant, as well as extract minerals at the same time. ZJH minerals is a professional thickener manufacturers for mining and mineral processing industry. Our thickener could be used for gold mining, lead and zinc mining, copper mining, etc.
The required depth of the thickener may be ascertained by computing the capacity of the thickening zone to contain a supply of solids equal to the total capacity of the tank for the number of hours required to …
THICKENERS. Thickeners in mineral processing can be monitored and improved by measuring density in the feed of the system, in the feedwell and in the underflow. …
The thickener could be "sliming" and will produce a dirty overflow combined with a low density underflow. If this is a problem, a reagent called a FLOCCULANT is added to the thickener feed. A …
The application of thickener modeling and optimization software in the wastewater treatment plant of mineral processing illustrates an optimal control operation with stable underflow concentration. ... it is possible to make the thickener overloaded and the mineral particle loss when the mud bed level is high enough. On the other hand, if …
The Workings of a Thickener. The invention of the Dorr thickener made possible the continuous dewatering of a dilute pulp …
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 ...
Thickeners ' a mysterious black box. Most of the world's minerals pass through solid-liquid separation in a thickener at some point in their processing. Thickeners are used to either: concentrate …
Chemical Engineering Journal, 2000. Research projects directed towards 'Improving Thickener Technology' have been conducted by the AJ Parker Cooperative Research Centre for Hydrometallurgy since 1988 through the Australian Mineral Industries Research Association with support from 25 Australian and international mineral processing …
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 …
High Rate Thickening is a process whereby mineral particles are flocculated, thoroughly mixed within a feedwell and then injected uniformly into a hindered settling zone in the …
Thickener is the common mineral processing equipment in the mineral processing plant, which is widely used in the concentration and dewatering of the mineral processing plant. However, in the practical operation, the fault rate of the thickener is up to 37%. Therefore, daily maintenance is the key point to reduce the fault rate of …

The alternative is to empty the thickener with a pump which is a long slow job. As you can imagine, a hard-hat or tool or large rock …
Mining thickeners are the common equipment for dewatering process in mineral processing plants. ... and covers an area of about 1/9 to 1/4 of that of the ordinary thickener, while the processing ...
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 …
The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake torque, rake height, solids settling rate and underflow rehology.
In mineral processing plants, thickening is intended to remove the water content of pulp so that the mineral processing products meet the requirements of the other processes. ... The main equipment includes center drive thickener, periphery drive thickener, high-efficiency thickener, deep-cone thickener, and inclined-plate …

This results in reduction in costs (mainly of energy and flocculants), reduction in waste volumes sent to …
Prominer can provide different kinds of thickeners include center driving thickener, peripheral traction thickener and high efficiency thickener. Our thickener is applicable for dewatering concentrate and tailing slurry in the mineral processing plant. It can improve the ore pulp from 20~30% to approx. 40~70%.
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.
