how is iron ore extracted
Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron (III) oxide, Fe 2O 3. The oxygen must be removed from the iron (III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.

iron processing
Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue.

How is pig iron manufactured from iron ore?
Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants.

how is iron extracted from its ore
What is iron ore? Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world’s iron and steel industries.
