The flotation of ilmenite in the onkilonite of vanadium-titanium magnetite using MOH as the collector was investigated.The effects of dosage of MOH,H2SO4 and sodium silicate on separation of ilmenite and gangue minerals were studied.The open and closed circuit experiments for ilmenite flotation were carried out on the basis of condition experiments.The results show that through the closed circuit experiment of "one roughing,one scavenging and four cleanings",the ilmenite concentrate with grade of 46.94% and recovery rate of 53.87% for TiO2 can be obtained.Production quality inspection shows that the MgO content in the ilmenite concentrate is relatively high and it only meets the requirements for 5th grade of ilmenite concentrate.The SEM results show that there exists a certain amount of olivine in the ilmenite concentrate,which is difficult to be separated and leads to increase in MgO content,eventually affecting the flotation index of the ilmenite concentrate.
