Complete answer: Iron is usually extracted from the oxide ore (haematite). It involves the following steps: Concentration: The ore is crushed in jaw crushers and the crushed ore is concentrated by the gravity separation process in which the crushed ore is washed in a stream of water when lighter sand and clay particles are Occurs as oxides, carbonates and sulphides. The common ores of iron are (1) Haematite Fe 2 O 3 (2) Magnetite Fe 3 O 4 (3) Limonite Fe 2 O 3.3H 2 O (4) Iron pyrites FeS 2 (5) Siderite FeCO 3. Though iron pyrites (FeS 2) is also common ore of iron, but because of its higher sulphur content, it is not used for the production of iron.

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 iron(III) 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 The extraction of iron occurs inside a blast furnace, a large 40 m tall steel tower. The waste gases produced from this process are carbon dioxide and nitrogen, neither of which is known as coke. Limestone is part of the charge used when extracting iron from its ore. Limestone is primarily composed of a calcium carbonate compound and is notLesson Explainer: Extracting Iron Nagwa

6. Occurrence of Iron Iron is very reactive and is found in nature in form of its oxides, carbonates and sulphates. The main ores are: i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The main iron ore is Haematite (iron (III) oxide Fe2O3). o The iron ore contains impurities, mainly silica (silicon dioxide). o Since iron is below Ores of iron Haematite: Fe2O3 Magnetite: Fe3O4 Iron pyrite: FeS2 Siderite: FeCO3 Limonite: Fe2O3.3H2O Extraction of iron from Haematite 1. Crushing and pulverization Big lumps of ores are crushed using jaw crushers to get crushed ore which is pulverized using a pulverizer or stamp mill to get powdered ore. 2.

The chief sources of iron are (i) Red Haematite Fe 2 O 3, Brown Haematite or Limonite 2 Fe 2 O 3. H 2 O, Magnetite Fe 3 O 4 (ii) Siderite or Spathic Iron ore FeCO 3 • The process of extraction of iron is fundamentally very simple as it consists essentially of the reduction of iron oxide by carbon. But as molten ironCarbon appears significant role in affecting the brittleness and hardness balance in Iron. To further reduce the Carbon content of pig iron, the pig Iron is melted again with scraps of Iron and Coke. This kind of Iron is called Cast Iron and has a lower Carbon content of 2-3 %. Cast Iron is harder than pig iron. Part 2:Describe the different steps involved in the extraction of iron

Iron is denser than slag so it settles beneath it. Iron and slag are tapped off separately at regular intervals and pure iron is collected alone. Waste gases such as carbon dioxide formed in the process and nitrogen and other gases from air blown in escape at the top of the. Extraction of Iron From Haematite Free download as PowerpointModern blast furnaces produce approximately 10000 tonnes of iron per day The process is demonstrated and explained below: Diagram showing the carbon extraction of iron.
