It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.

MoreWhat is The Procedure of Extraction of Iron From its Ore? Extraction of iron is lengthy process which commences from Concentration through calcination roasting. Water and other volatile impurities like sulphur and carbonates are removed by the process of Concentration.
MoreIron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

MoreExtracting iron from iron ore. In the 12th century, men started to mine iron ore from rock. They learnt how to recognize rock that contained iron ore and broke off pieces of rock by lighting fires against it, to make it brittle. The work was done from the surface down, excavating the rock in opencast mines and following the veins of ore.

More23-10-2017 The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).
MoreIron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.
MoreDETAILS OF EXTRACTION The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore Concentration of ore: In this metallurgical operation, the ore is concentrated by removing impurities like soil etc. The process involves the crushing and washing of ore.
MoreExtraction of Iron from Haematite. Step 1: The Iron ore is crushed and broken into smaller pieces, concentrated with gravity separation process (washed with water). Step 2: The raw materials are added into the top of the furnace : Iron ore (Haematite, Fe2O3), Coke (Carbon, C), Limestone (CaCO3) Step 3: It is heated by blowing hot air at the ...

More26-03-2020 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.
More04-09-2012 GENERAL OVERVIEW. Iron is extracted through a method called reduction. Raw materials used in the extraction of iron are: Oxygen has to be removed from iron (III) oxide chemically to obtain iron. Iron (III) oxide is reduced when oxygen is removed from it. A blast furnace is used for this process [Figure 4].
MoreIron ore, a type of coal called coke (which contains 85% carbon) and lime are added to the top of the blast furnace. Hot air provides the oxygen for the reaction. The temperature of a blast furnace can be up to 1200°C. The reaction takes place inside the furnace and molten iron is removed from the bottom.
