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.
About 95% of this iron is processed further to make steel, often by the open-hearth process or the Bessemer process, but more recently in the United States and other countries by the basic oxygen process or by an electric arc furnace. The balance is cast in sand molds into blocks called pigs.
We will discuss the extraction of iron from iron ore as an example. Extraction of iron. Iron atoms are found in the compounds FeO, Fe 2 O 3 and Fe 3 O 4 and in rocks like haematite and magnetite. South Africa is the seventh largest producer of iron ore in the world. Iron has been mined in South Africa for thousands of years.
The best known Iron ore is called Haematite (Haem - means Iron, as in Haemoglobin) It contains Iron Oxide and many impurities. It is dropped into the top of a blast-furnace along with Coke (purified Coal, almost pure Carbon ) and Limestone (Calcium Carbonate) .
Extracting iron from iron ore using a Blast Furnace The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air.
Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table.It is by mass the most common element on Earth, forming much of Earth's outer and inner core.It is the fourth most common element in the Earth's crust.. In its metallic state, iron is rare in the ...
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.
Iron can be extracted from ore with a high temperature coal fire. Iron can also be extracted by melting and refining scrap metals. Iron in ore is reduced to iron metal by heating with carbon.

Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO(OH)).. Iron-bearing groundwater typically emerges as a spring.The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the …
Iron is extracted from iron ore in a huge container called a blast furnace.Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
HOW THE IRON IS EXTRACTED FROM THE ORE. The second process is to smelt the ore, which operation is performed in " blast furnaces." The blast furnace is one which receives its supply of air for combustion, &c., in the shape of a strong blast from a pair, or more, of blowing engines.
Details for the extraction of aluminium, copper, iron and titanium are given in separate pages in this section. From ore to metal. What are "ores"? An ore is any naturally-occurring source of a metal that you can economically extract the metal from.
The main iron ore is called haematite. Haematite is iron(III) oxide - Fe2O3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium. Iron Extraction Process.
