These have confirmed that by using reduction techniques in a laboratory scale simulation of a mechanical oven it is possible to fully extract the iron, titanium and vanadium from the Ruoutevare titanium-magnetite ore.\n\nThe study was carried out by the MINPRO research laboratory at Strassa, Central Sweden. \n\nThe final product of high grade sponge iron powder contained 97% iron (Fe) and less than 0.5% titanium (TiO2), and 0.02% vanadium (V). These grades compare very favourably when compared with the grades of the initial mill concentrate produced from the Ruoutevare titanium-magnetite ore for the study carried out in the 1970s by the Swedish Geological Society showing Fe 53%, TiO2 12.3% and V 0.25%. \n\nThe initial tests show that subjecting the concentrate to sub-melting temperatures will reduce all of the iron which is not bonded to ilmenite, and by a subsequent magnetic separation technique, yield a sponge iron powder with high iron content and high metallisation level. By using petroleum coke as a reducing agent and adding soda, high metallisation levels have been achieved at 7750 C. \n\nFurther reduction tests show that, by adding a chloride (Na-, Cl-, and Fe- chloride respectively have been tested) a so-called segregation will be obtained with high selectivity against both ilmenite and vanadium. These tests produced very clean sponge iron powder with a grade of 95-97% Fe, 0.5% TiO2 and less than 0.02% V, with a metallisation level of 98% and the exchange of iron above 80%. The amount of iron sponge powder obtained is about 45% of the initial concentrate by weight. However, after extraction of Ti and V, the remaining iron can be recycled to the reduction proces...
