Treatment of iron ore slime for value addition

Research Highlights Iron ore slime which is a waste material contains 56% of iron. Two different chemical treatment methods and electrowinning method were separately studied to upgrade iron content up to 60% or above. Acid extraction and alkali extraction can upgrade iron content maximum 63% (w/w) and 65 % (w/w) respectively. Electrowinning directly produces high purity iron without
