In India, iron ores processing industries play a vital role in the Indian economy. During the washing and processing of iron ores, slimes less than mm are generated and discarded into the tailing pond. These slimes need processing as they cannot be used directly in blast furnaces. In the present investigation, a typical iron ore slime sample containing % Fe, % SiO2, and % ...

Mar 01, 2017· The above tables clearly indicates that (1) Concentrate grade depends on the mineralogical nature. Anhydrous iron oxides yielding better grades as compared to hydrated iron oxides (2) The grade and % Fe distribution in concentrate depends on % LOI, % Hydrated iron oxides and more so % of slime content.
and silica in iron ore leading to slime generation which are disposed off in tailing ponds. Slime in these tailing ponds contains iron values in the range of 45 60 %. Appropriate beneficiation process has to be explored to reduce the waste generation in mines and for the sustainable growth of the iron ore industry.
Indian economy. During the washing and processing of iron ores, slimes less than are generated and discarded into the tailing pond. These slimes need processing as they cannot be used directly in blast furnaces. In the present investigation, a typical iron ore slime sample containing % Fe, % SiO 2, and % Al 2O 3 was taken.
A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT. As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque. Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the bed a slope towards the centre of the thickener.
Fine and Coarse Iron Ore Beneficiation – An Evaluation into Global Technologies and Techniques L M van Niekerk1 1. Senior Process Engineer, DRA Pacific, PO Box 1283, West Perth WA 6005. Email: ABSTRACT The mining of iron ore is a high volume low margin business because the value of this commodity is
What shall we do for dewatering a placer iron ore tail, which contains lots of clay? 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 thicke
examined at pH 8 for beneficiation of iron ore slime and fines and visàvis the removal of gangue minerals. A typical example on the use of AN103(P)) showed that the surfaceactive agent significantly removes and disperses alumina containing gangue minerals in the suspension and increases the iron value in the concentrate of iron ore fines.
COPPER ELECTROREFINING ANODE SLIME: SEPARATION OF THE METALS. ... process of those concentrate all gold and silver are practically in the blister copper, which is ... The reaction system was quite effective on extracting the metallic values of the anode slime under study.
The beneficiation potential of the iron ore slimes produced from the washing plants and tailing ponds of Kiriburu mines assaying up to 60% Fe, % SiO 2, and % Al 2 O 3 is analyzed. To start with, the ore slime was characterized in sufficient detail to reveal that it is extremely fine — 80% below 110 μm and contains substantial amount of goethite (Fe 2 O 3 ·H 2 O).

iron ore slimes decreases with increasing pulp density and increases with increasing pH. The maximum settling rate of cm/s was obtained at pH 12 using a pulp density of 1% by weight. This may be attributed to the fact that at higher pH values all the particles (both iron .
Recovery of iron values from slimes and dewatering of the concentrate K. N. RAKSHIT National Mineral Development Corporation Limited, Hyderabad 500 028. ABSTRACT During crushing and wet processing of iron ore on an average 1518% slimes (100 mesh) are produced in the iron ore mines of Nationa Mineral Development Corporation (NMDC). About 50 to
Iron slimes generated after washing are dumped which contain significant amount of iron values and cannot be discarded. Therefore recovery of iron values from slimes has significance. In the present investigation, iron ore slime containing % Fe,
Nov 12, 2015· The process developed basically involves crushing, classification, processing of lumps, fines and slimes separately to produce concentrate suitable as .
iron ore concentrate dewatering ... journal of international academic research for The iron ore processing in India produces large amount of tailings as slime during exporters of iron ore in the world with the total resources of over 2852 billion tones of over a dewatering screen ...
slimes elsewhere. In order to recover additional values from these slimes, detailed beneficiation studies have been carried out on thickener U/F (Tailing) sample of beneficiation plant 2. The beneficiation of iron ore slime produced from washing plants and tailing ponds of Kiriburu mines was studies [1] using wet high intensity magnetic separator

Dec 21, 2015· Recovery of iron values from slimes results in economic benefit by utilisation of waste as a resource and minimizes the land requirement, surface degradation, ground water pollution, destruction of forests. These slimes after beneficiation are agglomerated (Pelletisation) and can be used as burden for the blast furnace.
From the process of excavation and the beneficiation of dumped iron slimes by a combination size reduction fines are generated. Fines can not be directly of suitable unit processes and also to reduce the ecological problem of contaminating the river water and green land. ... iron values.
