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.
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.. Thickeners may also improve the suspension of other ingredients or emulsions ...
Historically thickeners were introduced to the mining industry in 1905 when the beneficiation of ores by froth flotation was invented in Australia. In 1964 there was a project to reprocess the huge piles of tailings that accumulated over the years and recover the remaining copper . ... Ut and participated in a team that conducted test work ...
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.
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.
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.
Oct 09, 2015· Recently I visited a Coal Washery in Dhanbad District of India, there I saw this centre column supported thickener operating for Dewatering of tailing materials. For more videos related to Mineral ...

The following are some of the practical experiences of the gold mechanical mining machine tailings dry row team, we should pay attention to it in our work. These types of thickening tanks are divided into three types: center drive type, peripheral drive type and multilayer thickening tank.
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 ...
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
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 ...
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 ...
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 ...
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.
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 .
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 ...

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% ...
A look at the underground mining process The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies. Here''s how it works. Ore, rock containing . Continued
Chaulya, Prasad, in Sensing and Monitoring Technologies for Mines and Hazardous Areas, 2016. Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also ...
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.
