Abstract:
A method for producing pig iron by direct processing of ferrotitania sands, by the steps of: (a) mixing carbonaceous reductant, a fluxing agent, and a binder with titanium-containing materials selected from iron sands, metallic oxides, and/or iron ore concentrates, to form a mixture; (b) forming agglomerates from the mixture (c) introducing the agglomerates to a melting furnace; (d) melting the agglomerates at a temperature of from 1500 to 1760 C and forming hot metal with a slag thereon; (e) removing the slag; (f) tapping the hot metal; and (g) recovering the titanium and vanadium values.
