EXTRACTION OF IRON: APPLICATION OF METALLURGY
Metallurgy of iron is called the process of extraction of iron from its ores, and also the preparation of crude iron for its conversion to steel. In this field, extraction of iron involves the conversion of materials that have the capacity to be iron-bearing, and the conversion happens into metallic iron. Iron-making is a process and is a most ...

Metallurgy
Metallurgy process involves the refining of metals and the production of alloys of metals. The impurities present in the ore, which has to be separated in order to obtain desired metal from its ore during the process of extraction, are called gangue. A substance added in the furnace to remove the gangue present in the ore is called flux.

Metallurgy of Iron
Iron is the fourth most abundant ( about 5 % ) metallic element in the earth's crust . Because of its strong. affinity to oxygen, it is not found in nature in the elemental state but only in combined forms such as oxide. Iron is easily attacked by humid atmosphere. It is generally found associated with other metals like copper, cobalt and nickel.
