Treatment of slime in Hydrocyclone The iron ore slime first treated in a 2″ hydrocyclone to remove the ultra fines Multiple tests are conducted with different spigot and vortex finder diameters pulp density inlet pressure etc After each test both the underflow and overflow collected and analyzed for grade and yield
A typical high alumina containing iron ore slime from the eastern Indian sector containing % Fe % SiO2 % Al2O3 and % LOI have been evaluated to find out whether grinding of the
Previously iron based oxides/oxy hydroxides were widely explored for adsorption of As V [23] [24] Especially the iron based geo materials such as iron ore fines slime and tailings etc are used for the remediation of arsenic due to their low cost and abundant availability [25] [26] However these geo materials are less effective for
Iron ore is the basic raw material for iron and steel making India is among the leading producers of iron ore in the world and produces about 150 million tons per annum U S [] The total reserves of iron ore in India is around billion tons of this hematite ore is considered to be the most important iron ore because of its high grade quality and lumpy nature
The iron ore fines were ground to below 150 μm using a laboratory ball mill 2 ft x 2 ft in closed circuit grinding The particle size distribution of ground iron ore fine and slime samples were carried out by wet process using standard sieves Table 1 It is observed that 95% of the slime particles are below 45 μm
In India the tailings of iron ore beneficiation are dumped in slime ponds which is a major environmental concern In the present study a new beneficiation circuit was designed to recover the valuable minerals from the tailing effectively The present study involves the characterization of three different samples using chemical particle size optical microscopy
This study was performed on low grade iron ore slime contained % Fe with % silica and % alumina Detailed characterization data indicated that a substantial amount of the slime was
A typical high alumina containing iron ore slime from the eastern Indian sector containing % Fe % SiO2 % Al2O3 and % LOI have been evaluated to find out whether grinding of the
A typical high alumina containing iron ore slime from the eastern Indian sector containing % Fe % SiO2 % Al2O3 and % LOI have been evaluated to find out whether grinding of the
Molasses was used as an alternative binder to the bentonite binder The change in moisture absorption by pellets prepared with different iron ores and different molasses contents were investigated Iron ore properties exerted the major effect on pellet behavior and
Iron ore is the basic raw material for iron and steel making India is among the leading producers of iron ore in the world and produces about 150 million tons per annum U S [] The total reserves of iron ore in India is around billion tons of this hematite ore is considered to be the most important iron ore because of its high grade quality and lumpy nature
The role of chemical reagents to reduce moisture in iron ore fines is explored in the present work which includes ionic and non ionic surfactants The washing of iron ore in mineral processing plants result in moisture of about 11 14% in the fines and about 4% in the sized ore The moisture level goes up to 16% in the fines during the monsoon season
This technology cannot be implemented in India due to the very different nature of Indian iron ore slime Powder Technol 217 2012 pp 418 420 View in Scopus Google Scholar [14] A Vidyadhar Neha Kumari Bhagat Adsorption mechanism of mixed collector systems on hematite flotation
ABSTRACT The feasibility of producing direct reduced iron from cold bonded self reducing composite pellets constituted from beneficiated iron ore slime coke and different binders dextrin bentonite calcium lignosulfonate and carboxymethyl cellulose [CMC] was studied This was done using a design of experiments approach It was found that as received beneficiated
ABSTRACT A typical high alumina containing iron ore slime from the eastern Indian sector containing % Fe % SiO 2 % Al 2 O 3 and % LOI have been evaluated to find out whether grinding of the slimes will be beneficial or not for upgrading the slime to generate pellet grade concentrate with >64% studies indicated that there is
Download scientific diagram FTIR spectroscopy of iron ore slime from publication Reverse flotation studies on iron ore slime by the synergistic effect of cationic collectors Objective of
In India approximately 15 20% of Run of Mine ROM from any iron ore deposit is reported to slime dam as a byproduct of the iron ore beneficiation process The proportion of iron ore slime to ROM will increase in the future with a higher proportion of lean grade ores in ROM Furthermore tonnages of iron ore slime will increase with increasing demand of iron concentrate Presently
The flotation has been successfully applied to process the iron ore for the particle size Ps from 10 µm up to 150 µm The presence of the slimes Ps < 10 µm is harmful on the reverse
Iron ore slime is a micro fine of size below 20 µm in majority and rich in alumina and silica It is neither suitable for pelletization nor sintering Jhama coal is not also used in the iron making because of its poor caking property and thermal stability of lump Therefore the composite fluxed briquettes in a combination of these two materials were made to use this in low shaft furnace or
Chitradurga iron ore slime In case of Ukraine iron ore slime hematite and goethite are the main iron bearing phases and quartz is the main gangue phase Clay was found to be negligible in this sample Fig 2 Photomicrographs of Iron Ore Slimes A Chitradurga Iron Ore Slime B Jilling Iron Ore Slime C Ukraine Iron Ore Slime
A typical high alumina containing iron ore slime from the eastern Indian sector containing % Fe % SiO2 % Al2O3 and % LOI have been evaluated to find out whether grinding of the
The generation of iron ore slimes in India is estimated to be 10 15% by weight of the total iron ore mined The iron ore values are lost to the tune of 10 15 million tonnes per year
Iron ore slime 150 μm was obtained after scrubbing and wet screening of a low grade iron ore assayed % Fe with % Al 2 O 3 and % SiO 2 Size analysis revealed that 90% of the iron ore slime was having size less than 72 μm The isoelectric point of the iron ore slime was found to be at pH optimum condition
