Iron Ore By Hm Minerals

Grades of Iron Ores offered by us : -
Metallurgical uses :
* Most important use of iron is in the blast furnace for the production of pig iron. It is used in the furnace in the form of sinters and pellets as also lumpy ore. It is also consumed in the open health furnaces

Iron Ore Sinters :
* Sinters are produced from iron ore fines for uses in the blast furnace
* The Steel Plant uses the sizes + 10 mm less than 5% minus 8 mm 65%. Minus 1 mm 40%. The Fe content should be 61.5% A 0.5%

Iron Ore Pellets :
* High-grade iron ore fines are used for the preparation of pellets
* Iron content in the ore has got to be very high and gangue low to confirm to the quality of pellets. The content generally is 66% Fe, SiO2 + A12O3 a 3%, Sulfur and Phosphorus 0.05% each

Utilization of Quartz a magnetite rocks :
* The only project of this kind is Kudramukh deposits where material containing + 38% Fe from the oxidized zone is mined and treated to produce magnetite concentrates and pellets. These concentrates contain + 67% Fe

Non a Metallurgical Uses : -

Pipe Contain :
* Especially calibrated iron fines have been found to be useful as a high-density aggregate for pipe coating. Such coated pipes are essential for the transport of crude oil from offshore wells

Utilization of magnetite in coal Washery :
* Magnetite is also used in the coal washery. It is used in granulated form. The magnetite content in the ore should be + 95%
