Dry Process Of Iron Ore Extraction
extraction of iron from its ores, iron dressing, reduction roasting is the process of heating iron ore strongly in dry air for drying the ore and expelling humidity, It is used to increase the percentage of iron in the ore and for the oxidation of some impurities such as sulphur and phosphorus.the principles of selective reduction and extraction of iron from lean and complex ores without melting have been developed. the iron is reduced directly inside the lattice of complex oxides at a iron: pure iron does not have a variety of uses. but alloys of iron such as steel are highly useful. alloys are nothing but a mixture of different types of metals. alloys of irons are used to make cars, nails, bridges etc. We are going to discuss in details about the different types of iron in the extraction of the iron part.

the slag is lighter than molten iron and to floats on the surface of the iron. the formation of prevents the oxidation of iron. zone of reduction:-this is the most important zone and has temperature of In this zone Fe is reduced to iron by co in three steps. CO COextraction of aluminium aluminium is a reactive metal which sits above carbon on the reactivity series. It cannot be extracted from its ore by carbon reduction, so electrolysis is used. diagram showing the extraction of aluminium by electrolysis recycling metals: ironextraction OF iron ore occurrence: iron does not occur in the native state as it is oxidized easily. iron in elemental state occurs in meteorites. iron is an important constituent of hemoglobin of blood. iron is also present in plant and animal tissues.
