Extraction of Iron – Study material for IIT JEE askIITians

Preparation of Wrought Iron. This is done by heating cast iron with haematite (Fe 2 O 3) which oxidizes C to CO, S to SO 2, Si to SiO 2, P to P 4 O 10 and Mn to MnO. Fe 2 O 3 + 3C → 2Fe + 3CO. Where CO and SO 2 escape, manganous oxides (MnO) and Silica (SiO 2) combine to form slag.. MnO + SiO 2 → MnSiO 3. Similarly phosphorous pentoxide combines with haematite to form ferric phosphate slag.

HISTORY OF METALLURGY

Cast iron in the east: 513 BC: Thus far in the story iron has been heated and hammered, but never melted. Its melting point (1528°C) is too high for primitive furnaces, which can reach about 1300°C and are adequate for copper (melting at 1083°C). This limitation is overcome when the Chinese develop a furnace hot enough to melt iron, enabling ...

Jan 19, 2021  Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes.. Bauxite is the general name given to the hydrated oxides of aluminum.
