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.

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 ...
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.
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.
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.
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 ...
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% ...
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 ...
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 ...
offered to enhance performance of existing thickeners and clarifiers. tHiCkener design MIP Thickeners and Clarifiers are designed to operate continuously for 24 hours per day. Process selections are based on test work coupled with our vast experience in the field of thickening. It is our belief that a thickener .
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 ...
Sep 13, 2013· gravity to the thickener and shall have the energy to aid mixing of flocculant solution with it. The feed well is sized adequately to take care of the venting of the entrapped air in the feed slurry.

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 ...
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.
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 ...
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 ...
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 .
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.
