Research Progress on the Extraction of Niobium Resources in Bayan Obo AITranslate
Abstract AITranslate
The existing niobium extraction processes of Bayan Obo rare earth-niobium-iron polymetallic ore are reviewed,including beneficiation process and metallurgy process,and the advantages and disadvantages of each process are also analyzed and discussed.The conventional beneficiation and metallurgy processes have never been able to solve the problem of efficient separation between niobium-bearing minerals and iron-bearing minerals with similar properties,so that high-grade niobium concentrates(or ferroniobium products)can’t be obtained.The new idea combining the methods of beneficiation and metallurgy,by actively changing the properties of raw materials and preferentially directionally converting multiple niobium-bearing minerals into niobium-bearing minerals with single and easily selectable properties,makes it possible to obtain high-grade niobium concentrates by subsequent beneficiation methods,which might be expected to solve the problem of efficient utilization of niobium resources in Bayan Obo.
