| This material is also known as Scrubbed (Beneficiated) Iron Ore.
Since availability of quality iron ore is decreasing every day, the
iron ore is first scrubbed before roasting in the beneficiation
process of pellet plant. In the process of scrubbing, the maximum
amount of gangue and unwanted materials are removed hence its physical
and chemical properties are changed. This will give better performance
for production of Iron Ore Pellets and Sponge Iron.

This can also be used for extraction of oil & other material
manufacturing because of its Specific Gravity
increases up to
4.9. |
