Iron concentrate flotation desulfurization process: harmful impurities in iron concentrates are generally in the form of pyrite and pyrrhotite. Sulfur in the form of pyrite can be removed by flotation or magnetic separation of xanthate In addition, sulfur in the form of pyrrhotite is difficult to remove because of its strong magnetic properties and its floatability is susceptible to various factors. Research and practice at home and abroad have proved that the surface of pyrrhotite is easy to oxidize (formation of iron hydroxide), muddy, magnetic agglomeration, etc., which greatly reduces its floatability. For this reason, in the flotation desulfurization, it is generally used. Acid scrubbing surface, dispersing agent dispersing, demagnetization, multi-stage activation, enhanced harvesting and other measures to improve the removal rate.
