Nov 28, 2016· In the former tailings circuit, two stages of the thickening process were needed to treat tailings at 3.3Mtpa. Now just one high rate thickener can treat more than 5.2Mtpa, to produce 53-60%w/w solids underflow density, which represents an improvement of between 9-15% in pumping efficiency and tailings system capacity, according to Tisco.
Jul 13, 2016· How a Thickener Works. 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, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...

May 24, 2016· Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500 ...
A thickener/clarifier drive unit supplies the torque to rotate the rake arms through the thick sludge. The drive is usually made of cast iron because of its durability. Usage Examples Thickeners and clarifiers are often used in water and wastewater treatment plants to …
May 15, 2020· Indian mining industries primarily depend upon high-grade fines mainly because of two factors, one is lack of beneficiation infrastructure and high cost of low-grade fines, the second one is lack of proper tail disposal system. Due to lapses in our policies, miners get better premium by selling high-grade fines over low-grade fines. This restricts the flow of low-grade fines into the market ...
Increasing efficiency of thickener operation in concentrate plant of iron ore mine using coagulation-flocculation. J Adv Environ Health Res 2016; 4(3): 146-54. Introduction1 In general, 2 to 3 tons of water is consumed to Iron ore mine of Jalalabad-Zarand is one of the produce one ton of ore.
May 01, 2015· "Combined use of primary and secondary thickeners in iron ore mining has rarely been implemented." A large 295-foot diameter primary thickener is integrated with a secondary paste thickener located three miles away at the paste disposal facility.
Khumani Iron Ore Mine paste disposal and water recovery system The use of conventional large-diameter (90 m) traction thickening technology was a proven process at the nearby Assmang Beeshoek iron ore operations some 60 km away. However, concerns over high evaporations rates in the area, lack of suitable sites for a conventional tailings ...
A portion of this water is recycled to the process while the remainder is lost. This necessitates optimization of dewatering systems particularly in arid and semi-arid mining regions. In this paper the bench and full-scale flocculation behavior of iron ore tailings is investigated in order to improve the dewatering performance of tailings ...
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

The utility model discloses a pulp thickening device in an iron ore separation process. The pulp thickening device comprises a high-efficiency sloping panel thickening hopper and a high-efficiency thickening machine, wherein the high-efficiency thickening machine is positioned below the high-efficiency sloping panel thickening hopper, and an overflow hole of the high-efficiency sloping panel ...
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
In the concentrate thickener, the purified slurry is thickened prior to being pumped to a disc filter. Again the addition of polymer aids in the separation and thickening process. The disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry …
As a result, we determined how each alumina type of iron ore would perform during processing. The results Understanding the influence of different ore characteristics to optimise processing . These insights improved the company's understanding of the influence of ore material on the final product, and the desirable ore properties for processing.

Mar 28, 2015· Typically, iron ore operations use continuous thickeners equipped with a raking mechanism to remove solids. Several variations of rakes are normally used in thickeners. When concentrates are being thickened, underflow from the thickener (concentrate) is collected and is further treated in a ceramic disc vacuum filter.
Figure 2. Water balance of a high-density thickener in an iron ore concentrator plant. The most common problems in thickener operations include the presence of suspended solids in the recovered water and the density or percentage of solids of the thickener discharge outside the set targets.
The method of operating on a batch process is still practiced in small flow industries but its shortcomings are obvious so once the plants grew larger the need for continuous operation became inevitable. The trend in this direction started at the late 19th century when heavy duty applications such as iron ore taconites, hematite, coal, aluminum ...
