01 Iron Ore Desulfurization Processing Stage grinding – stage processing desulfurization. The grinding fineness has a large influence on pyrite-bearing iron ore benefication. Different grinding fineness inflluences the dissociation degree of mineral monomer and washability.

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

2016-7-8  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 Desulfurization of Magnetite Ore by Flotation

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

Effects of Multi-stage Grinding Process and Grinding ...

2015-1-1  It follows that the optimal regrinding fineness is 90% -0.045mm. In the circumstances, the S grade of iron concentrate reaches 0.98% with the TFe recovery of 48.50%. Therefore, the separation process of multi-stage grinding is a promising way for iron recovery and desulfurization of the high-sulfurous iron ore. Fig. 5.

Desulfurization Behavior of Iron-based Sorbent with

2019-12-12  The sulfidation behaviors of iron-based sorbent with MgO and MgO-TiO2 are studied under different isothermal conditions from 623 to 873 K in a fixed bed reactor. The results of sorbents sulfidation experiments indicate that the sorbents with MgO and TiO2 additives are more attractive than those without additives for desulfurization of hot coal gas. The sulfur capacity (16.17, 18.45, and 19.68 ...
