Effects of Electromagnetic Action on Melting and Separation of Niobium Concentrate AITranslate
Abstract AITranslate
In view of the characteristics and actuality of unbalanced utilization of Bayan Obo niobium concentrate,the electromagnetic action is introduced to realize the dual objectives of efficient separation of metallic iron resources and comprehensive utilization of niobium carbide in Bayan Obo niobium concentrate.In this research,the effect of electromagnetic action on the melting and separation of the niobium concentrate was studied by using self-designed electromagnetic melting and separation device.The results indicate that the electromagnetic action can promote the separation of slag and iron after the reduction of niobium concentrate to reduce the residual iron in the slag.When the current frequency is fixed,the yield of metallic iron increases significantly with the increase of the current intensity.When the current intensity is fixed,the iron yield decreases with the increase of the current frequency.The electromagnetic action promotes the contact between niobium carbide and iron.Under the same current frequency,the content of niobium carbide in iron increases significantly with the increase of the current intensity,while it decreases obviously with the increase of the current frequency under the same current intensity.The magnetic field produced by low frequency and high intensity current can improve the dispersion effect of niobium carbide in iron phase,and the niobium carbide particles in iron are obviously dispersed.
