Abstract：The sulfur content is 0.6%in Shandong iron ore concentrate, the sulfur is mainly hosted in the magnetic pyrite, and it is closely related with the magnetite. By testing the different pulp pH value, activator, catching collectors on the flotation of pyrrhotite separation effect influence, the roughing reagent system was determined: combination collecting agent (butyl xanthate∶ammonium butyl aerofloat=2∶1) is 200g/t, pulp pH value is 6.5-7, activator of copper sulfate is 60 g/t, electioneering agent is 60 g/t, foaming agent is 30 g/t. It optimize dosage of electioneering agent and flotation time in the flow test, by a rough two sweep closed-circuit flotation process, the sulfur content in iron concentrate fell to 0.2%.
