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 9294% iron and about 35% of carbon along with other impurities. Pig iron has limited uses, so it is sent to steel plants where the content of carbon is further reduced. The iron is then combined with manganese, nickel and other such ...

Extracting iron The blast furnace. Iron is extracted from iron ore. in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2 O 3. The oxygen must be ...
· We extract iron form it's ore so that we can use it for a lot more things. For Example, this process makes wrought iron which can be used for ornamental .
· Extraction of Iron using blast furnace and various types of Steel: Iron ore is reduced to iron by heating them with coke (a form of carbon) in blast furnace. As mentioned earlier, common iron ores are hematite (Fe2O3) and magnetite (Fe3O4). The air blown into the bottom of the blast furnace is heated using the hot waste gases from the top. Heat energy is valuable, and it is important to ...
· Extraction of iron or its metallurgy is the process of obtaining this metal in a form where it can be put to practical use, and this process of extraction consists of three stages: Ore dressing, Reduction of ores and Iron production. Extraction of Iron from its ores. The ore dressing. The aim of ore dressing is increasing the concentration of iron in the ore by removing the unwanted impurities ...
· 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.
The classical production route of steel from pig iron, however, not only utilizes new equipment such as the oxygen converter, but an altogether new technology has been developed which allows the direct transformation of iron ore by hydrocarbons. The greatest technical changes are associated, of course, with uranium processing, and from the start, both military and civilian uses developed on ...
Extracting Iron from Iron Ore in a Blast Furnace The metal iron and its alloy steel is one of the most important substances used by man. Humans have been discovering the metal's uses science 3500BC. Huge quantities are used in the construction industry to construct of all kinds of vehicles. The most common from of iron known is the oxide. The Iron is extracted from the ore that contains the ...
Answer: Usually, limestone (calcium carbonate, CaCO3) is "calcined" in a lime kiln, where it is heated to form lime (CaO) and CO2 gas. The lime is then used in both steelmaking furnaces to refine liquid iron into steel, and also on ladles as slag to further refine the steel. It absorbs impuritie...

· It is also widely used in many other industries. Coal also serves as fuel in the extraction of iron from iron ore and for the production of cement. Due to a rise in demand for coal, many mining techniques have evolved to extract the fossil fuel. A largescale mining of coal requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. Depending on their properties, coal is ...
· Smelting is used to extract iron from iron ore, Smelting uses heat and a chemical reducing agent like charcoal. The carbon (from the charcoal) or carbon monoxide derived from it removes oxygen from the ore to leave the metal. The heat causes the sand to melt and flow away from the Iron. The temperature has to be kept low enough so that the iron does not melt
The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The loion and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
