Hematite Processing by Flotation

Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves Deposits of comparatively lower grade iron ore that remain relatively untouched or by passed, are now most important because of increase in
