How is Iron Extracted from Iron Ore Actforlibraries

The furnace is initially charged with pre-calculated quantities of coke limestone (CaCO3) and the iron oxide to be reduced to pure iron. The main reactions that take place in a blast furnace are fairly simple. Coke which is a form of carbon is produced by heating coal in the absence of air. It is inexpensive and it reacts with oxygen from

Iron Fe (Element)PubChem

Iron is the cheapest and one of the most abundant of all metals comprising nearly 5.6 of the earth s crust and nearly all of the earth s core. Iron is primarily obtained from the minerals hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). The minerals taconite limonite (FeO(OH)·nH 2 O) and siderite (FeCO 3) are other important sources.

 · For example the oxide of iron can be reduced by carbon monoxide as follows Fe 2 O 3 3CO → 2Fe 3CO 2. In this extraction a basic flux limestone is used. Since the silica gangue present in the ore is acidic in nature the limestone combines with it to form Calcium silicate (Slag). Question 12. Give the basic requirement for vapour phase

Extraction of Iron (examples answers activities

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.

How Is Iron Extracted From the Earth Reference

 · 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.

Processes and Procedures in the Extraction of Iron

 · 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.
