In this zone Fe 2 O 3 is reduced to iron by co in three steps. 3Fe 2 O 3 + CO → 2Fe 3 O 4 + CO 2 Fe 3 O 4 + CO → 3FeO + CO 2
Extraction of Iron from Haematite Step 1: The Iron ore is crushed and broken into smaller pieces, concentrated with gravity separation process (washed with water).
2012. 7. 24.· Extraction of iron is based on the reduction of HAEMATITE (Fe2O3) with carbon.. DETAILS OF EXTRACTION. The process of the extraction of iron is carried out by the following steps: Concentration of ore. Calcination or Roasting of ore. Reduction of ore. Concentration of ore:
2016. 3. 25.· The extraction of iron for iron ore (haematite), using coke, limestone and air in a blast furnace. Iron is displaced from its ore (haematite) by carbon (from coke). 2Fe2O3 + 3C 4Fe + 3CO2 It is also displaced by carbon monoxide.
2017. 3. 27.· Iron is extracted from its ore in the blast furnace. The main iron ore is called haematite. Haematite is iron ( III) oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica ( silicon dioxide ). Limestone ( calcium carbonate) is added to the iron ore. which reacts with
2019. 12. 27.· Iron is extracted from its ore, haematite in a blast furnace. The ore is led into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.
