CBSE NCERT Notes Class 12 Chemistry Isolation of Elements

Cast iron is different from pig iron and is made by melting pig iron with scrap iron and coke using hot air blast It has slightly lower carbon content about 3 and is extremely hard and brittle Wrought iron or malleable iron is the purest form of commercial iron and is prepared from cast iron by oxidising impurities in a reverberatory furnace lined with haematite...
