packaged settling unit with a conical sludge hopper. The Lamella Gravity Settler / Thickener (LGST) design is a high-rate gravity settler combined with a circular, picket-fence sludge thickener/scraper. The settler section utilizes the same counter-current flow principle and the inclined plate design used in packaged Lamella Gravity Settlers.
Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow ...
Faq About Copper Ore Processing - maternapioxii. Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and ...

The hindered settling zone consists of a pulp of fairly uniform consistency, which is near the same solids concentration as the feed stream.

Typically, the capital cost of a conventional thickener (eg, 30m dia unit for a 500,OOOtpa gold treatment plant) would increase the cost of the treatment plant by 10-15%; the use of a high rate thickener (10m dia unit for 500,OOOtpa) would result in a 3-4% increase only in the plant cost and achieve the same water and cyanide recovery.

In a continuously operated thickener, there are different zones of concentration. The topmost dear zone is free of solids and comprises the liquid that eventually escapes over the weirs. The next zone is called the feed zone although this zone does not necessarily have the same concentration of feed solids.
The use of High Rate Thickeners has gained wide acceptance in the mineral treatment industries. The design of these units is characterized by an efficient deaeration and flocculation chamber, and of the flocculated feed solids into a preformed floc bed zone. By these means the settling process is accelerated and consequently High Rate Thickeners achieve...

Optimizing settling by using Lamella® Lamella® Gravity Settler requires only one tenth the space of conventional clarification equipment with the same settling capacity. This means faster settling because the effective gravity settling area of the inclined plate design equals each plate's area projected on a horizontal surface.

conventional thickener compaction zone p. conventional thickener hindered settling zone p. Concepts of Conventional and High Capacity Thickeners Conventional Thickener The name Conventional Thickener is used for equipments with short feedwells where the flocculated pulp leaves the feedwell and enters into the settling zone of the thickener well above the sediment level. thickener compaction zone
The thickening process is a fundamental step in modern mining separation processes. Thickening is the separation of suspended particles from a liquid by gravity settling. For effective thickener control six measurements are critical bed mass inventory bed level underflow . Get Price
Jan 18, 2013· Cemented backfill or surface deposition of paste tailings is increasingly being considered as a simple and effective means of reducing the hazards of conventional slurry deposition and recovering water for recycle. Although gravity thickening has been widely used in the mineral industry to increase the solids concentration of tailings, the accurate prediction of the concentration distribution ...
Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below. High rate thickener feed wells are designed to disperse flocculants thoroughly into the feed end to admit the flocculated slurry into the settling zone of the thickener without destruction of the newly formed floccules.
