  • Beneficiation of Iron Ores – IspatGuru

    03/04/2014· 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) However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiationThe process of iron ore beneficiation has two complementary goals and these define the methods used to refine it The iron content of the ore needs to be increased and gangue, which is native rock and minerals of lesser value within the ore itself, must be separated out Methods such as screening, crushing, and grinding of iron ore are often used in various ways to purify it, along withWhat Is Iron Ore Beneficiation? (with pictures)Iron ore is a basic raw material used for pig iron production in the blast furnace The ore burden preparation plays a very vital role in the improvement of the blast furnace productivity Ore processing has been employed to the ore burden prepa ration by way of sizing the ore and beneficiation For better blast furnace productivity, the ratio of maximum to minimum size of lump ore chargedbeneficiation therefore, is to improve the iron content
