of the gangue mineral in iron ore slimes and fines. Beneficiation of slime and fines The efficacy of the surface-active agents AN103P and AD200 was examined at pH 8 for beneficiation of iron ore slime and fines and vis- -vis the removal of gangue minerals. A
The present paper describes the beneficiation studies of Iron ore slime from Karnataka, India through dispersion and selective flocculation in presence of surfactants and polymers with a view to produce pellet grade fines. The slime sample had a feed grade of
iron ore by utilizing slime. The results from the reference research work had showed that the application of beneficiation process for the iron ore slime in India may lead to the sustainable growth of iron ore industries and it has also opened up answers for several questions regarding waste utilization and disposal strategies.
As most of the work reported above, the iron ore slimes were relatively rich in Fe content.Beneficiation andor utilisation of slime are still not practiced industrially in India. The volume of generated slimes is large and its grade is often reasonably high.
After beneficiation iron ore availability can improve by about 50. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative 1. Utilisation of low grade iron ores after beneficiation. 2. Reduction in slime loss by recovery of iron values from slimes. 3.

iron ore slime. 2. Experimental Iron ore slime collected for this study was screened by wet sieving technique into three broad size classes such as coarser than 50 m, between 50 to 25 m and finer than 25m. This classification is based on the prevailing under-standing that existing beneficiation
The result showed the possibility of slime enrichment of Bolani iron ore mines and its use in sinter making. An industrial scheme for beneficiation and recovery of enriched grade fines from slime for the Bolani iron ore mines has been proposed. INTRODUCTION The iron ore processing plant of Bolani has throughput capacity of 3.44 million tonesyear.
Beneficiation of low-grade fine-grained hematite ores becomes increasingly important due to rapid depletion of high quality iron ore resources. However, fine particles, especially ultra-fine particles, make efficient beneficiation of these ores more difficult. Therefore, methods to reduce the influence of fine particles must be considered to achieve better beneficiation performance.
Iron ore slime -150 m was obtained after scrubbing and wet screening of a low grade iron ore assayed 42.7 Fe with 12.5 Al 2 O 3 and 13.68 SiO 2. Size analysis revealed that 90 of the iron ore slime was having size less than 72 m. The isoelectric point of the iron ore slime was found to be at pH 4.21.The optimum condition
Vinay Jain Beena Rai Umesh V. Waghmare Venugopal Tammishetti Pradip Received 10 January 2013 Accepted 5 May 2013 Indian Institute of Metals 2013 Abstract Beneficiation of alumina rich iron ore slimes is 63 kcalmol between hematite and gibbsite surfaces. a major challenge for the Indian iron ore
recovering the iron values using beneficiation techniques. The source of iron ore slime used in this investigation is generated in laboratory from scrubbing washing of low grade iron ore from eastern part of India. METHODOLOGY Materials A composite sample was generated after de-sliming the -150 m material by hydro cyclone.
The experimental results show that it is possible to raise the iron content up to 64.17 at a yield of 37.3 with a simultaneous decrease in the alumina content, down to 1.17.Earlier work indicates that beneficiation of iron ore slime containing very low iron and high alumina and silica is quite difficult.
