Carbon monoxide then reduces iron in the ore to iron metal carbon monoxide ironIII oxide carbon dioxide iron 3CO g Fe 2 O 3 s 3CO 2 g 2Fe l The temperature where the reduction takes place is above 1500 °C Iron falls to the bottom of the furnace

May 15 2020 · The cast iron is usually extracted from its oxide ore haematite This process involves the following steps 1 Concentration The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size

Oct 23 2018 · Reduction of Fe2O3 by using a mixture of carbon monoxide and hydrogen water gas that is produced from natural gas 93 methane in the Midrex furnace to produce Spongy iron Spongy iron is the iron mixed with impurities where it is produced from the midrex furnace and it has holes similar to that in the sponge 2CH4 CO2 H2O → 3 CO 5 H2

Iron ore haematite IronIII oxide Fe 2 O 3 A compound that the iron is extracted from Coke Carbon C Used as a fuel and reacts to form carbon monoxide needed to reduce the ironIII oxide

May 15 2020 · Extraction of Iron The cast iron is usually extracted from its oxide ore haematite This process involves the following steps 1 Concentration The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size The oxides of iron are reduced by carbon monoxide to iron

The still impure molten iron is mixed with scrap iron from recycling and oxygen is blown on to the mixture The oxygen reacts with the remaining impurities to form various oxides The carbon forms carbon monoxide Since this is a gas it removes itself from the iron This carbon monoxide can be cleaned and used as a fuel gas

Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite Fe2O3 The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes
