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.
Bench flotation experiments on a skarn type magnetite ore from Kazakhstan containing 2.0 to 3.5 percent sulphur were performed to systematically investigate the flotation behaviour of sulphides in general and pyrrhotite in particular. Specific emphasis was drawn on establishing the optimum grind size for sulphide liberation and the influence of

Crushing: The raw ore less than 200mm is crushed to 10 0mm through a two stage closed circuit process including a jaw crusher and a vibrating screen. Grinding: Closed circuit grinding of the broken ore, grind the ore to 200mm 70%, and then enter the flotation process;
