Vale has 19 iron ore mines and 10 industrial beneficiation plants in the QF region. These produce almost 200 million tons per year of iron ore, which represents approximately 70% of the total production in the region (DNPM, 2012; Vale S.A., 2012). Production is forecast to increase approximately 10% between 2013 and 2017, and 50% by 2030.

High-rate bolted thickener for iron ore, 18 m in diameter ANDRITZ bolted thickener INNOVATIVE MODULAR HYBRID DESIGN • Custom-sized thickeners are designed to minimize site installation work • Smart 3D CAD models make it possible to improve accuracy and enable early clash detection • Design conforms to applicable international laws,
design calculations to determine the required thickener area, the most important design parameter, and ultimately the maximum steady state underflow concentration that is possible for a given solids throughput. In addition, the capital cost ofa thickener will be dependent on the calculated required settling area. Therefore,
We design a thickener (2*15) m at the first stage of dewatering. The thickener underflow solid percent is 50%. It's notable that we consider adding flocculant in the thickening stage. For more dewatering of thickener underflow we want to use a chamber filter press, but the tests have showed that the filter cake moister reaches to 30%.
The following examples illustrate the effect of the system consideration on selection of the paste thickener. Iron Ore Tailings.

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.

Several years ago, WesTech Engineering was involved in the design of the thickening process at the South African Khumani iron ore miner. The company's specialists developed a two-stage processing scheme: the first stage with high-performance thickeners with a diameter of 90 m was launched together with the mine itself in 2008, the second ...
Lastly, Tenova Delkor reported that it recently delivered a 22-m-diameter ore tailings thickener to London Mining's Marampa iron-ore project in Sierra Leone. The company noted that this was its third order for Marampa, with the two previous contracts covering …
Iron ore slime system with a particle size -75 micron. What will be the crucial parameter in scaling up of the thickener? for e.g., if the thickener is of 10L volume, can it be scaled up to 10000L ...
Purpose of Iron Ore Beneficiation The iron ore extracted from the mtnes are benificiated to separate out the valuable mineral content. If iron content is nearly or more than 60 per cent the ore is only crushed and screened to size and can be sent directly to metallurgical plant without beneficiati on. In case ore containing low Fe content, it ...

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 ...
The uses of thickeners in a beneficiation process are five fold, they are. Readily available fresh water for pre-thickener and post-thickening operations. Maximum recovery of ultra-fine solids, so they can be filter pressed and used for other applications. Prevents the problem of sludge run-off. Environmental foot-print is drastically reduced.
The above are the problems in open pit iron ore mining and measures to improve mining production safety. For mining production enterprises, it is necessary to choose a qualified mining company to design the iron ore mining process, which has a positive effect on improving the economic efficiency of mining enterprises as well as production quality.

Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

Equipment Design. There are three main types of thickeners/clarifiers: bridge support, column support, and traction. In a bridge support thickener, such as the one shown below, the rakes and drive mechanism are suspended from a bridge that spans the diameter of the tank. They are usually only economical for diameters of fewer than 100 feet.
