Abstract In off-gas desulfurization in sinter plants, dry systems consisting of a sorption process for the separation of sulfur dioxide and a fabric filter for final dedusting are normally used. As a rule, hydrated lime is the base sorbent although sodium bicarbonate can be an alternative. Mechanical and flow properties of the residues produced are relevant for the design of handling and ...

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.

Residue samples investigated were from dry second-stage off-gas cleaning systems of industrial scale iron ore sinter plants. The residue samples A and B were from desulfurization units in which Ca(OH) 2 was used as a reactant. Sample A was from a sinter plant where the first off-gas cleaning stage was an EP, whereas sample B originated from a sinter plant where a cyclone was installed for dedusting.
