A pilot-scale study of selective desulfurization via urea

Nov 08, 2016 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 pilot-scale experiment was carried out in a commercial sintering plant.

The Desulfurization of Magnetite Ore by Flotation with a

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.
