Jun 13, 2014· Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 820 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
Iron ore sample (1mm) by Blaine apparatus and BET method for MSPL, Hospet, Karnataka. Specific surface area determined by Blaine apparatus was found to be cm2/gm, while by BET method it was m2 /gm. Specific surface area determined by Blaine apparatus BET method.
Most ore deposits are mined for the exploitation of metals. A metal is any chemical element (or elements in an alloy) having a characteristic luster, is opaque, and is a good conduc tor for heat and electricity. Approx imately 80 of our chemical elements are metals. Heavy metals have a density 5 g/cm3.
The mine was estimated to hold billion tonnes of proven iron ore reserve (grading % Fe) and billion tonnes of probable iron ore reserve (grading % Fe) by the end of 2012. Production in 2012 was million tonnes and the life of the mine is projected to continue up to 2053.

Estimating the lump to fines composition split in iron ore production J. E. Everett Faculty of Economics and Commerce, The University of Western Australia Abstract Iron ore is mined, crushed and separated into lump and fines components, which are sold as separate products. Quality (and therefore value) depends upon the
Why is Iron Ore Valuable? Iron ore is a rock from which the metal iron is extracted. About 98% of the world's iron is used to produce steel.. Pure iron is an element and a soft grayishwhite metal. Other than meteorites that fall from the sky, iron is never found by itself in nature.
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
