Barsua iron ore mine in India has adopted Remco Jigs for beneficiation of low- . ores. A Batac jig is installed to reduce alumina content of iron ore fines from Noamundi mines by M/s Tata Steel. Jigging of iron ore fines was also taken up as . concentrating iron ore of selected size range was investigated using the jigging.
Mar 26, 2014 . However, only few iron ore plants in India are using the beneficiation techniques while dealing with fines. Mostly, washing followed by classification is adopted to prepare the calibrated lumps and fines. The washing technique can hardly enhance the iron content by 2 to 3 percent with marginal reduction in.

KarnataNa, many are of lowYgrade which require beneficiation to produce an acceptable feed for steel.
Indian Iron Ore fines do not have domestic market as fines cannot be directly used in blast furnace or DRI for making steel. We can use these fines . Iron ore fines and slimes present in tailing dams can be efficiently agglomerated and stabilized using native microorganisms from an environmental angle. Lala Behari Sukla.
ABSTRACT. Indian iron ore is generally friable in nature that results in generation of significant quantity of fines (around 35%) during mining and processing in the country. The ratio of lumps to fines produced in the country is 2:3. During washing and sizing of the ore, slimes with less than 0.21 mm size are generated and.
