Flotation Desulfurization

Enhancing fine particle recovery in flotation and its

The separation of sulphides in the environmental desulphurization process is performed via a bulks ulphide flotation. However, the recovery of fine particles is known as being low in flotation processes (ex. Trahar and Warren, 1976). Therefore, the following question was given:

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.
