Abstract
Iron ores containing ilmenite and which also contain vanadium and possibly chromium are reduced in the presence of a reducing agent and an alkaline compound such as sodium carbonate at a temperature of 650-800 DEG C so that the ilmenite remains substantially unaltered, the magnetite reduced to sponge iron and the vanadium compound, and the chromium compound, if present, are reduced to alkali vanadate and chromate. The residue is lixiviated to remove the soluble compounds and the ilmenite separated from the reduced iron by magnetic separation. The solution containing the vanadate &c. may be treated in known manner to produce vanadic and chromic acids.ALSO:Iron ores containing ilmenite and which also contain vanadium and may also contain chromium are reduced in the presence of a reducing agent and an alkali compound such as sodium carbonate at a temperature of 650-800 DEG C. so that the ilmenite remains substantially unaltered while the magnetite is reduced to sponge iron and the vanadium compound and the chromium compound, if present, are reduced to alkali vanadate and chromate. The reduction is carried out in closed vessels preferably a rotary kiln and by means of reducing gases with or without admixed carbon in the charge. The residue is lixiviated to remove the soluble compounds and the ilmenite separated from the reduced iron by magnetic separation.
