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 …
2. Introduction To Pelletisation Process Pellets are spherical balls formed by the agglomeration of natural or ground iron ore fines in the presence of moisture and binder These green balls of 5 – 20mm size are then dried, preheated and fired at 1250 – 13500 C Bonding is developed between the fine ore particles at such high temperatures Additives …
4. Continued… Carbon Contents In Iron: . A certain proportion of carbon (between 0.002% and 2.1%) produces steel, which may be up to 1000 times harder than pure iron. Crude iron metal is produced in blast furnaces, where ore is reduced by coke to pig iron, which has high carbon content. Iron chemical compounds, which include …
