CHEM-GUIDE: Occurrence and extraction of iron

02/01/2018  Extraction. Extraction of Iron is done in many steps like oxidation, combustion, fusion, reduction, etc. During extraction cast iron is formed first which is then converted to wrought iron. Hematite is the ore that is used for extraction of cast iron. The ore is crushed into small pieces and is washed with water to remove the sand particles. Then the washed ore is heated in the presence of
