Iron Extraction and Purification / Steel ChemKey

2020-9-9  The molten iron from the bottom of the furnace can be used as cast iron. Cast iron is very runny when it is molten and doesn't shrink much when it solidifies. It is therefore ideal for making castings – hence its name. However, it is very impure, containing about 4% by weight of carbon. This carbon makes it very hard, but also very brittle.

Extraction of Iron from Haematite Grade 12 Science

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. FeO + CO → Fe + CO 2. (Solid state) From the bottom of blast furnace, molten slag and molten iron are tapped out. This iron is impure and is called cast-iron or pig-iron.

How Is Iron Extracted From the Earth? - Reference

2020-3-26  Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
