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.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".

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.
Mar 14, 2014 · The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, loion and
ZIMSEC O Level Combined Science Notes: Extraction of iron: The blast furnace. After iron ore is mined it is send to the blast furnace Iron is extracted from its ore in a blast furnace . The structure of a blast furnace. Image credit scool .uk.
Iron ore is most often found in the forms of hematite and magnetite. Learn what makes those types of iron ore different and make an informed investment. Did you know that there are different types
The iron pillar of Delhi is an example of the iron extraction and processing methodologies of early India. Iron ore is then treated with these gases in a furnace, producing solid sponge iron: Fe 2 O 3 + CO + 2 H 2 → 2 Fe + CO 2 + 2 H 2 O. Silica is removed by adding a limestone flux as described above.
The increasing demand of iron ore at home and abroad further stimulates the development of the global iron ore beneficiation industry. As one of the leading enterprises in domestic mineral processing industry, Xinhai has been dedied commitment to the research and development of iron ore process, technology and equipment for more than 20 years.
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. 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
5.4 describe and explain the main reactions involved in the extraction of iron from iron ore (Haematite), using coke, limestone and air in a blast furnace.
EXTRACTION OF IRON INTRODUCTION Iron is extracted from its ore called HAEMATITE (Fe2O3). oxide PRINCIPLE OF EXTRACTION Extraction of iron is based on the reduction of HAEMATITE (Fe2O3) with carbon.. DETAILS OF EXTRACTION The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of
How can the answer be improved?
The production of iron from its ore involves an oxidationreduction 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.
Know about the various processes used for extraction of iron and formation of its alloys with the help of study material for IIT JEE by askIITians.
The last quantities if iron are suggested to be precipitated as hydroxide in order to remove the undesirable contaminants by coprecipitation. Solvent Extraction of Iron in a Zinc Plant. The conceptual flowsheet in Figure 2 shows how the process for extracting iron by a carboxylic acid is integrated into the hydrometallurgical processing of zinc.
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace.
Most metals are extracted from ore. found in the Earth''s crust. An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. Extracting iron
Jul 21, 2014 · Iron oresuch as haematite, which is a form of Iron (III) oxide, Fe 2 O 3 Role of limestone (calcium carbonate) in the extraction of iron. Limestone removes impurities present in the iron ore. This is achieved because, at high temperatures, calcium carbonate will undergo thermal decomposition to calcium oxide.
Iron: Pure iron does not have a variety of uses. But alloys of iron such as steel are highly useful. Alloys are nothing but a mixture of different types of metals. Alloys of Irons are used to make cars, nails, bridges etc. We are going to discuss in details about the different types of iron in the extraction of the iron part.
