Production of FeNi from high iron nickel ores
2012-9-7 The paper deals with the operation of FeNi-Furnaces when smelting high grade FeNi from ores containing more than 20% Iron oxide. Principles of operation have been discussed and compared to the operation of furnaces pro-ducing low grade FeNi in the well known non-selective smelting process. FeNi-SMELTING The Rotary Kiln — Electrical Furnace RKEF)

2019-5-17 The carbothermic smelting reduction process of ilmenite ore at high temperature was investigated by thermodynamic calculations in conjunction with smelting experiments. Based on thermodynamic calculations, conducting the smelting process at a higher temperature was recommended to achieve a larger amount of FeO reduction, i.e., higher Ti-enrichment, as less precipitate and thus large amounts of ...
