Abstract: A new combined magnetizing roasting-separation-smelting process of niobium enrichment from No.2 ore body of Baotou niobium-bearing iron ore has been developed. Using magnetizing roasting-magnetic separation-plasma smelting, a kind of middle grade ferroniobium of 22%~32% Nb and Nb/P>30 has been obtained and total niobium recovery ratio is 61.l%. This combined process has great economical potential because of its shorter flowsheet and more efficient operation.
