Iron Production
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first ...

Explain the extraction of iron from haematite.
The spongy iron moving down in the furance melts in the fusion zone and dissolved the impurities like C, Si, Mn, phosphorus and sulphure. The molten iron collects at the bottom of furnace. The lighter slag floats on the molten iron and prevents its oxidation. The molten iron is removed and cooled in moulds. It is called pig iron or cast …

Bauxite (aluminum ore), haematite (iron ore), copper pyrites, zinc blend, etc. Relationship: All ores are minerals, but not all minerals are ores. Ores are a subset of minerals. Economic Value: Generally not used for metal extraction. Used specifically for extracting metals.
The main ore used for the extraction of iron is:
Option A is Haematite. The name haematite is derived from the Greek word haima which means blood in accordance with the red colour of the ore due to the presence of iron (II) oxide or ferric oxide. Thus, haematite is an ore of iron. Option B is Calamite. Calamite is an ore of zinc containing two different minerals present in the ore distinctly.

Mineral
This group includes haematite, a source of iron. Brazilianite. Sulphates contain the sulphate group SO 4. Sulphates commonly form in evaporites where highly salty waters slowly evaporate, allowing sulfates and halides to precipitate where the water evaporates. Sulphates also occur where hot waters are forced through the rock, as with geysers.
