The Desulfurization of Magnetite Ore by Flotation with a ...

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.

Abstract. The iron ore sintering process is the main source of SO 2 emissions in the iron and steel industry. In our previous research, we proposed a novel technology for reducing SO 2 emissions in the flue gas in the iron ore sintering process by adding urea at a given distance from the sintering grate bar. In this paper, a pilotscale experiment was carried out in a commercial sintering plant.
