gcse 2. Blast furnace extraction of iron recycling, steel
Iron ore is used to make iron and steel eg haematite and magnetite. Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides the carbon is known as the reducing agent. Coke is a cheap and readily made reducing agent.

3 Extracting Iron IGCSE Chemistry Google Sites
Iron is only a moderately reactive metal but it is less reactive than Carbon. Because of this is can be smelted displaced from Iron compounds by heating with Carbon (coke). Iron compounds are found in rocks we call rocks with high percentages of Iron compounds Iron ore.

Iron Pure iron does not have a variety of uses. But alloys of iron such as steel are highly useful. Alloys are nothing but a mixture of different types of metals. Alloys of Irons are used to make cars, nails, bridges etc. We are going to discuss in details about the different types of iron in the extraction of the iron part.

GCSE CHEMISTRY Extraction of Iron Haematite
Extraction of Metals. Extraction of Iron. 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 the silica to form molten calcium silicate

Extraction Of Iron By Haematite Henan zhengzhou Mining
Extraction of Iron Iron is extracted from its chief ore Haematite Fe 2 O 3.The various steps involved in the process are as follows 1. Crushing The ores are crushed in jaw crusher and powdered in ball mills. 2. Concentration The crushed ore is washed with steam or cold water to remove clay and sand. The washed ore is then concentrated by electromagnetic separation process.
