Direct iron production at molten metal state from iron oxides by the sole application of electrical energy represents a possible route to decarbonize steel industry. Although chemically simple, this reaction is difficult to implement due to the problem of the multiple valence states of iron and to an operating temperature above 1811 K. Thermal, chemical, and electrical conditions have been ...
The contribution of the manuscript would be more important if the iron concentration in ore could be determined by using of machine learning, not just classification of ores. It seems that 45 spectra used for each ore are randomly chosen, so this randomness is a part of determined principal components.
