Flotation reagents for iron ore beneficiation. iron ore flotation process and reagents Iron ore is a mineral which is used after extraction and processing for the production of iron and steel The main ores of iron usually contain Fe2O3 70 iron hematite or Fe3O4 72 iron magnetite Contact Supplier.
The collector is the most important reagent used in the iron ore flotation process. The function of the collector reagent is to promote affinity between mineral particles and air bubbles by formation of a waterrepellent coating on the surface of the mineral particle. Most collectors in current use are heteropolar they contain both a polar

ABSTRACT Recently beneficiation of iron from lowgrade ores with high impurities has been a matter of discussion. Flotation is one of the most effective technologies for the upgrading of lowgrade finely grained iron ores. This method can also be applied to reduce the impurities content in magnetite concentrates obtained using wet low and highintensity magnetic separations. In this paper
