Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin ferrum) and atomic number 26 It is a metal, that belongs to the first transition series and group 8 of the periodic tableIt is by mass the most common element on Earth, forming much of Earth's outer and inner coreIt is the fourth most common element in the Earth's crust Pure iron is very rare on the Earth's crust.
Extraction Process of Aluminium from Bauxite Ore
Alumina Extraction Problem In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch.
IRON AND STEELThis page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke.Extraction of Zinc from Zinc BlendeZinc can be electroplated on iron by keeping iron article as cathode, zinc as anode and znso4 solution as electrolyte On passing current a layer of zinc is coated on iron article b By metallizing Zinc can be directly applied by dipping iron article in molten zinc this process is generally used for galvanization of iron.Extraction of Zinc from Zinc BlendeZinc can be electroplated on iron by keeping iron article as cathode, zinc as anode and znso4 solution as electrolyte On passing current a layer of zinc is coated on iron article b By metallizing Zinc can be directly applied by dipping iron article in molten zinc this process is generally used for galvanization of iron.Iron Extraction ProcessIron Extraction Process In the blast furnace process, the first step on the way towards heavy plate, pig iron is produced from iron ore The composition of the ore and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstahl AG.Extracting ironExtracting iron The blast furnace Iron is extracted from iron ore in a huge container called a blast furnace Iron ores such as haematite contain iron(III) oxide, Fe 2 O 3 The oxygen must be.Extracting iron and copperThis method of extraction works because carbon is more reactive than iron, so it can displace iron from iron compounds Extracting a metal by heating with carbon is cheaper than using electrolysis.Metallurgic ProcessesThe pig iron was melted in a running out furnace and then run out into a trough This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough The product of this process was a white metal known as finers metal or refined iron.
Extraction Of Iron
