  • 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 sulde 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.

  • Crystals Free Fulltext Desulfurization Ability Of

    With the consumption of high-quality iron ore resources, the grade of iron ore raw used in the iron making process has gradually decreased. The high aluminum raw materials has led to an increase in the Al2O3 content in the blast furnace slag, which has affected the normal operation of the blast furnace. The activity of the components involved in the desulfurization reaction is an important ...
