The first large scale iron ore jig beneficiation plant in India was commissioned in 2006 at Noamundi in the state of Jharkhand. Tata Steel is already operating a 300 tph fine ore jig iron ore plant there. Patnaik Minerals also followed the pattern and started constructing 100 tph fine ore jigging machine at
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines.

BENEFICIATION OF IRON ORE 2.3 Processing of Iron ore in India 8 2.4 Slimes of Iron ore 11 3. BENEFICIATION PLANT STUDY OF NOAMUNDI IRON ORE MINE 14 The aim of this project is to propose methods for utilization of low grade iron ore especially Banded
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
Barsua iron ore mine in India has adopted Remco Jigs for beneficiation of low-grade iron ore fines. Bateman’s Apic jig is being used in iron ore mines of South Africa and has demonstrated how the technology is suitable for the separation of fine ferrous ores. A Batac jig is installed to reduce alumina content of iron ore fines from Noamundi
Uses The technology developed is for beneficiating low grade iron ores ores and the calibrated lumps, fines & concentrate so produced are used for iron & steel making. Salient Features The process so developed basically involves crushing, classification, processing of lumps, fines and slimes separately to produce concentrate suitable for lump
The technology developed is for beneficiating low grade iron ores. The calibrated lumps, fines & concentrate so produced are used for iron & steel making. Salient Features : The process so developed basically involves crushing, classification, processing of lumps, fines and slimes separately to produce concentrate suitable as lump and sinter

Iron Ore Industry. Most commercial grade iron ore bodies do not require beneficiation to produce a saleable product. Low grade iron ore bodies can be beneficiated using the DEC Flotation column and produce a saleable product at a low production cost per ton.
The beneficiation plant design capability is 7MT/annum, adopted the process technology of stage grinding, respective separation for rough and fine ore, gravity separation--magnetic separation--reverse flotation, so that on the base of crude iron ore grade 29 per cent can get the beneficiation index of concentrate grade more than 66.55 per cent
Iron ore pelletisation. BRPL is in operation in producing iron ore pellets from iron ore concentrates after beneficiating low grade iron ore fines. The low grade fines with Fe less than 56-57% are beneficiated at beneficiation plant through grinding, gravity & magnetic separation process to produce high grade iron ore concentrates with 63-64% Fe.
Low grade iron ores cannot be used as such for the production of iron and steel and need to be upgraded to reduce its gangue content and increase its Fe content. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB).
Australia, India and South Afric a. Low grade run of mine and/or dump ores are being pro-cessed with alljig®-, allflux®- and gaustec®-separators as the core equipment. This paper describes the project of a 1500 t/h beneficiation plant for haematitic iron ore in India. The data presented show the entire project from flowsheet development to plant
Two fine low-grade iron ores were used in this series of tests. The first ore consisted of an ultrafine Fe ore tailings sample with a D50 of 20 µm and the second sample of an itabirite iron ore sample with a D50 of 60 µm. Both samples present challenges during their beneficiation and cannot be

ST Equipment & Technology and Ramadas Minerals Pvt. Ltd. in India understand this challenge well. Ramadas Minerals contacted STET to perform testing of a low grade barite / quartz sample produced at the APMDC barite mine in Andhra Pradesh, India. The material was a low grade tailings product from the mining process.
Growth of Steel Industry, especially in China over the years despite the depletion of high grade Iron Ore has taken place on the strength of technologies of Beneficiation, Sintering and Pelletisation of Iron Ore Fines, which enhances the productivity of the blast furnaces in Steel making and hence lowering the cost of steel production.
