  • PURIFICATION OF IRON ORE (BY MAGNETIC SEPARATION

    Iron has been known since prehistoric times Indians were familiar with its extraction It may be called the king of metals The Ore of Iron can easily be separated from Gangue by this method Large amount of ore can be purified by this method It has two rollers, one is magnetic roller & other one is nonmagnetic roller When ore is dropped on the magnetic roller, it moves through conveyersIron processing, use of a smelting process to turn the ore into a form from which products can be fashionedIncluded in this article also is a discussion of the mining of iron and of its preparation for smelting Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties It constitutes 5 percent by weight of the Earth’s crust, and it is theIron processing | Britannica
