How to extract iron from its ore The method Three substances are needed to enable to extraction of iron from its ore The combined mixture is called the charge: Iron ore, haematite often contains sand with iron oxide, Fe2O3 Limestone calcium carbonate Coke mainly carbon The charge is placed a giant chimney called a blast furnace The blast furnace is around 30 metres high and lined

May 22, 2009 The Step by Step Process of Extracting Iron from its Ore using the Blast Furnace with details of Chemical Reactions Question Answers based on the process of extraction of metals

The rock containing iron ore is ground and the ore is extracted using magnetic rollers Fine grained iron ore is processed into coarse grained clumps for use in the blast furnace Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon A mixture of iron ore and coal is then heated in a blast furnace to produce

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 blast furnace is used for extracting iron from its ore In summary, A mixture called the charge iron ore haematite, limestone calcium carbonate, and coke pure carbon containing the iron ore

Extraction of Metals Extraction of Iron Iron is extracted from its ore in the blast furnace The main iron ore is called haematite Haematite is ironIII oxide Fe 2 O 3 The iron ore contains impurities, mainly silica silicon dioxide Limestone calcium carbonate is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace

Iron is extracted from the ore containing the maximum amount of iron This is found near the surface of the Earth Iron ore is converted to iron by various processes The most common process is the use of a blast furnace to extract pig iron Pig iron comprises of about 92 94 iron and about 3 5 of carbon along with other impurities

Jun 14, 2009 This includes iron extraction for the production of steel from iron ore, and copper extraction and other base metals from their ores Smelting uses heat and a chemical reducing agent, commonly a fuel that is a source of carbon such as coke, or in earlier times charcoal, to change the oxidation state of the metal ore

Feb 04, 2014 Extraction of iron from its oxides:In a Blast furnace Oxide ores of iron, after concentration through calcination/roasting are mixed with limestone and coke are fed from its top Hot air is blown
