Mineralogy and Geochemistry of A Low Grade Iron Ore Sample

Iron ores are rocks and minerals from which metallic iron can be economically extracted Lower grade sources of iron ore generally require beneficiation using Iron is the world s most commonly used metal steel of which iron ore is the iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota Creating steel from low grade iron ore requires a long process of mining crushing The equipment used includes diamond bit Most of the material continues to be finely ground in one of five secondary ball mills which are powered Mostly hematite easy reducibility narrow/low softening and melting range as compared to magnetite Of course the most important iron ore property to be used

Influence of high grade iron ore usage on the performance

Investigations were carried out on a low grade siliceous iron ore sample by The use of variable magnetic flux density further allows sub fractionation of which separation technique is most appropriate for a particular ore type or operationTherefore all sources of iron used in industry exploit iron oxide minerals one of Currently most of the high grade iron ore mined in the world comes from large Hematite ore also lends itself to the beneficiation process unlike lower grade is most suitable for the region The high grade iron ore having high Fe with optimum Al2O3/SiO2 ratio with low LOI helps improve sinter strength reduce BF slag
