thickeners means that they are well represented throughout the world. With a wealth of experience and a large database of test work and commissioning, DELKOR can provide accurate estimates on sizing of a thickener for most applications. Bench scale testing on representative samples can be carried out at our numerous laboratories around the world
A thickener is a machine that dewaters slurry, separating the liquid from the solids. The solids'' particle size range in thickeners is generally from mm to a few microns. The finer the particle size, the slower settling and compaction rate. Actually, thickeners simply concentrate the solids, achieving underflow solids densities from 20% ...
INFOGRAPHIC Everything you need to know, miningMar 11, 2015· This infographic covers everything you should know about copper porphyries, a deposit type responsible for about 60% of copper, 95% of molybdenum, and 20% of gold produced todayprinciple of work energy efficient thickener for mining useHydrochloric Acid Thickener Equipment,Gold Mining Machine, Hydrochloric Acid Thickener .
Thickener development and general history Sedimentation technology was originally developed in the mining industry. Prior to the development of the continuous thickener, batch gravitational settling was employed. In such batch operations, dilute feed was pumped into a tank continuously until a clear overflow was no longer obtained.
Sep 07, 2000· These thickeners offer properties including improved flow and leveling. So far, associative thickeners have only been known for application in waterborne coatings, notably dispersion paint. The trend to reduce the emission of organic solvents led to .
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
The engineering characteristics of tailings are in most instances influenced by the degree of thickening and the method of deposition. It is therefore essential that while investigating the properties of tailings that the physical characteristics and material parameters ( beach slope angles, particle size segregation, water recovery) that can occur as a result of varied deposition ...

Depending on the requirements of the residue storage facility, further thickening, filtration and/or neutralisation stages are employed prior to it being pumped to the bauxite residue disposal area. 5. Precipitation. In this stage, the alumina is recovered by crystallisation from the pregnant liquor, which is supersaturated in sodium aluminate.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...
HighRate Thickeners, or Clarifiers, recover immediately reusable process water for mineral and aggregate producers, as well as environmental contractors. Thickeners are beneficial in a variety of applications, including areas where water is in short supply or very expensive, recirculated water is not suitable for reuse in a plant, ponds are located on minable reserves, or ponds must be ...
International Mining''s monster April issue, including the annual paste supplement is now with the printer. One article for which there was insufficient space is by Outotec''s Andrew McIntosh. He notes that "the sizing of equipment which achieves design requirements and is not conservatively oversized can influence both the financing of a project as well as its long term operational ...
Feb 12, 2008· MIXERS AND THICKENERS FOR THE MINING INDUSTRY. Feb 12, 2008. 1. views. Lightnin Africa is a division of international group, SPX Process Equipment and has supplied well over sixty large mixers into the African mining industry over the past four years, with some 25 units being sold to the Ashanti group of mines.
ALDRUM drum thickeners can be adjusted to suit particular sludge thickening needs. The most efficient thickening is found by varying the feed rate, the polymer type and dosage, flocculation mixer speed (if fitted), drum speed, angle of the drum, and the spraying interval. A variety of different filter cloths are also available for new applications.

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flatbottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...
Thickeners: How they Operate. The most common solidsliquid (S/L) unit operation is thickening. A wide variety of thickeners are used including conventional, deep well, paste, high rate and clarifiers which is a thickener subclass used for removing solids from turbid or very low % solids waters.

The increase in flocculation efficiency realised in high rate thickeners may increase in a bulk settling rate 2 to 10 times over that obtained in a conventional thickener, thus reducing the unit area requirements by a similar factor. The corresponding volume may be 4 to 15 times smaller than with conventional thickeners in the same application.
In mining applications, thickening through sedimentation is applied to both the product and tailings streams to recover water. This water is recycled in the process. Figure 1: Thickening. Particle properties affect the degree of separation that can be achieved with sedimentation. Size, shape, surface chemistry, and solids density all influence ...
