Read MoreExtraction of iron metal from iron oxide ore is carried out by heating with coke and flux (calcium carbonate). Flux is a slag forming substance. It converts infusible impurities into fusible slag.Fe2O3 (s) → Fe (s) + 32 O2 (g) is not a spontaneous process. Fe2O3 is converted to FeO at about 400°C. FeO is converted to Fe at about 800 - 1000°C.
