BENEFICIATION OF LOW/OFF GRADE IRON ORE: A REVIEW

Abstract

The present investigation deals with 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 upgradation 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.  Among all applied technique it was found that the iron content of the concentrates is obtained with reduction in SiO2 and Al2O3. After various beneficiation processes Fe content could be enriched from 38% to 60%.
