Sulfur Reduction Of Iron Ore Mineral Processing Flotation

Iron ores with a high content of impurities, such as sulfur, have been processed [2]. Pyrrhotite (Fe1 xS) is a kind of common sulfide which exists in magnetite ore as an associated mineral with little industrial value. The contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore smelting process.

    The contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore processing. This study utilized froth flotation to float pyrrhotite away from magnetite using collectors of xanthate and dixanthogen. It was found that xanthate or dixanthogen alone could not achieve selective separation between pyrrhotite and magnetite in flotation.The flotation process is governed by a complex phenomenon occurring on the surface of mineral particles and air bubbles formed in the water phase. From the practical point of view, the hydrophobicity and bubble mineralization are perhaps the two most important factors in flotation and govern the system kinetics and selectivity of flotation.
