Abstract
1397200 Reduction of iron in oxidic materials ICI AUSTRALIA Ltd 23 March 1973 [4 April 1972] 14162/73 Headings ON and C1A [Also in Division C7] The iron content of an oxidic material containing a non-ferrous oxide is reduced to metal by heating in the presence of an alkali metal or alkaline earth metal chloride as flux, a solid carbonaceous material, and HCl (which may be formed in situ), to a temperature below that at which a slag is formed, the partial pressure of HCl above the reaction mixture being maintained at or above 10<SP>-4</SP> atmos. The oxidic material may be an ore, slag or metallurgical residue containing Mn, Cr, Ti, V, Nb, Ta or Al, and is preferably ilmenite, which may be pelleted with the flux and carbon. The HCl may be added as a gas or may be generated from FeCl 2 , Cl 2 or organic Cl compounds, or by decomposition of the flux. Other fluxes may be present, e.g. borax, Na 2 CO 3 , CaCl 2 , MgCl 2 , CaF 2 , CaSO 4 , Na 2 SO 4 , apatite or dolomite. The ratio of ore to flux may be 50 : 1 to 1 : 5. The process may be operated at 900-1200‹ C, the solids being fed by gravity through a vertical kiln in countercurrent to the gases. The Fe may be separated by magnetic separation or air or water elutriation, preferably into 3 fractions. The Ti rich fraction is used in the chloride process and the middle fraction is used in the sulphate process or recycled.
