Extracting iron from iron ore using a Blast Furnace Introduction 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 cokeIron can be extracted by the blast furnace because it can be displaced by carbon This is more efficient method than electrolysis because it is more cost effective Three substances are needed to enable to extraction of iron from its ore The combined mixture is called the charge Iron ore haematite often contains sand with iron oxide Fe2O3 Limestone calcium carbonate Coke mainly

Blast Furnace Slag is formed when iron ore or iron pellets coke and a flux either limestone or dolomite are melted together in a blast furnace When the metallurgical smelting process is complete the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non metallic product called blast furnace slag During the period of cooling From the bottom of blast furnace molten slag and molten iron are tapped out This iron is impure and is called cast iron or pig iron This iron is impure and is called cast iron or pig iron Have a question

Blasts furnaces are used for smelting during the production of metals such as iron lead zinc and copper A blast furnace works by blasting hot air up through the furnace while fuels limestone and ore move continuously through the top of the furnaceGGBFS is obtained as a by product in the extraction of iron from it ore The process of extraction of iron is blast furnace The slag that is obtained on the iron ore is separated and cooled down slowly which results in the formation of nonreactive crystalline material

Iron pyrites FeS 2 is not directly used as an ore for the extraction of iron because it contains quite high percentage of sulphur The residual FeO 3 formed during burning of FeS 2 is reduced to iron in blast furnace as already discussed COMMERCIAL FORMS OF IRON There are three commercial forms of iron which differ from each other mainly in their carbon content Cast Iron or Pig Iron 11 24 32 This feature is not available right now Please try again later
