Aug 152020 The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides.

Iron processing - Iron processing - Ores: Iron ores occur in igneousmetamorphic (transformed)or sedimentary rocks in a variety of geologic environments. Most are sedimentarybut many have been changed by weatheringand so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxidesand iron ores consist mainly of hematite (Fe2O3)which is
This iron can also be used in steel production or purified further to give wrought iron. Waste gas mixture that exudes from the furnace contains majorly nitrogen30% carbon(II)oxide and about 10% carbon(IV)oxide. These waste gas mixture is used in pre-heating the air blast and the iron ore at the initial stages of the extraction process.
May 292020 The technology created two major developments in iron production. Firstblast furnaces were now able to make cast iron for the production of hollowware such as pots and kettles. Secondin the new indirect process cast iron could be converted into wrought iron with a higher yield of iron from the ore than the direct process.

The next stage in the production chain is the processing of bauxite into aluminaor aluminium oxide - Al 2 O 3- a white powder. The most common process for making alumina from bauxite is the Bayer processwhich was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer
Extracting iron from iron ore . In the 12th centurymen started to mine iron ore from rock. They learnt how to recognize rock that contained iron ore and broke off pieces of rock by lighting fires against itto make it brittle. The work was done from the surface downexcavating the rock in opencast mines and following the veins of ore.

The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
