6. Occurrence of Iron Iron is very reactive and is found in nature in form of its oxides, carbonates and sulphates. The main ores are: i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The main iron ore is Haematite (iron (III) oxide - Fe2O3). o The iron ore contains impurities, mainly silica (silicon dioxide). o Since iron is below carbon in the reactivity …
In the Blast Furnaces, we melt iron ore into liquid iron at high temperatures. Iron ore has a sand-like structure that can put out the fire in the furnace. Because of that, you can't put it in the furnace just like that. The ore is first baked to make it into porous chunks, or sinters. This is done in the Sintering Plant. In the Pelletising ...
