    Request PDF Beneficiation of Iron Ore Slimes using Optimized Hydrocyclone Operation Beneficiation is the process of separating iron ore from the gangue particles like alumina, silica.The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine ( 0.010 mm) clay-rich slimes simply follow the water.

    These fines, slimes and tailings is a big problem for the iron ore beneficiation industries. over these contain a good amount of iron values which can be recovered by further beneficiation.These slimes to make it suitable for iron making process. The other advantage appears to be that the slimes do not require energy intensive grinding process for liberation of desired minerals. The slimes contain significant amount of ultra fine particles comprising mainly Alumina and to certain extent silica [2].

    In addition to this, depletion of high grade iron ore, stringent environmental regulations involved in opening of new mines, problems involved in handling, disposal of tailings (slimes), and utilizing of iron ore at 45 Fe as a cut-off fixed by Indian Bureau of Mines, it is the need of hour to effectively beneficiate low grade iron ore.Slime in these tailing ponds contains iron values in the range of 45-60 . Appropriate beneficiation process has to be advanced to reduce the waste generation in mines and for the sustainable growth of the iron ore industry some. Major reason for difficulty in beneficiation of BHJ is revealed from characterization studies which show the.

    Apr 03, 2014 Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 iron, hematite) or Fe3O4 (72 iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total.The beneficiation potentials of two Indian iron ore slime samples by flotation technique using both cationic and anionic collectors are investigated. The direct and reverse flotation of slimes using oleic acid and dodecylamine as the collector have been studied using both conventional cell and flotation column to upgrade the iron content.
