BENEFICIATION OF LOW/OFF GRADE IRON ORE: A REVIEW

An attempt has been done to collect information regarding methods apply for the recovery of iron values from various Mechanical & Chemical techniques. The main aim of this review paper to determines the Industrial practice and fundamental research activities for the up gradation of low/ off grade iron ore. Practically mechanical separation and float flotation methods applicable in different composition and size of iron ore with different recovery percentage of Fe. the Iron content in the concentrated ore is obtained with reduction in SiO2 and Al2O3 after beneficiation operation on it. After various beneficiation processes Fe content could be enriched from 38% to 60%.
