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 ...

If, for some reason, the thickener's settling rate is too slow, as in the case of the grind being so fine or you are dealing with clay rich ore and now 911 Metallurgist is a trusted resource for practical insights, solutions, and support in mineral processing engineering, helping industry professionals succeed with proven expertise. | Thickener ...

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.

The objectives of thickener control are varied, but in most instances, the objective is to dewater the slurry, reclaim the clear overflow for reuse in the process, and produce a thickened or more dense underflow, which can either …

In the mineral processing process, the concentration of the slurry directly affects the efficiency and effect of the subsequent process. By thickening the slurry with a thickener, the concentration of the slurry can be increased, the processing volume of the subsequent process can be reduced, and thus the production efficiency can be improved.

Analysis of a range of industrial thickeners from the processing of gold ores, red mud, coal tailings, potable water sludge and clay suspensions shows that current mathematical models generally...

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. Combined with a flow meter, the …

Gravity thickeners generally retain 80−90% of the solids in the thickened product stream, depending on the sludge characteristics and the efficiency of the preceding conditioning stage. The sludge characteristics also govern the solids loading rate (SLR), which is the rate in kg/d at which the sludge dry solids enter the process per unit process cross-sectional area.

They must provide operating flexibility to meet process needs. Such factors multiply the decisions which must be made prior to the selection of a thickener. Most thickener designs, suitable to minerals applications, are based on the separation of -65 mesh, 2.7 specific gravity solids containing slimes.

This process uses starch (depressant) and amine (quartz collector) as reagents to promote the separation of the contaminant mineral (quartz) from the iron-bearing mineral. The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener.

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.

Thickener troubleshooting in mineral processing plants involves identifying and resolving issues that hinder the efficient separation of solids from liquids. One common issue is poor flocculation, which can be caused by incorrect flocculant dosage, improper mixing, or changes in slurry characteristics. Conducting jar tests to determine the optimal flocculant …

During thickener operation, feed enters the feedwell, via a feed pipe or open launder. In order to promote settling, it is increasing to dissipate this energy. In some cases, flocculants or coagulants are added to the feed to agglomerate particles and improve settling. ... High Rate Thickening is a process whereby mineral particles are ...

Calculating Thickener Area: Thickener area required is then cal­culated by applying above determined data in the following formula: A = 1.333 (F – D)/R. A = Thickener area in square feet per ton of dry solids thickened in 24 hours. F = Initial density (Parts Water to …

Tailings, the by-products of mineral processing, often contain fine particles and water.
