· Once the pig iron ore has been produced it is sent to an basic oxygen furnace or BOF to turn it into steel. Molten iron from a blast furnace is "charged" (poured from a ladle) into the BOF
Chat OnlineIron 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. Pig iron has limited uses so it is sent to steel plants where the content of carbon is
Chat Online· a) The ore of aluminium bauxite is concentrated by this method. The bauxite ore is contaminated with impurities of silica (SiO 2) iron oxides (Fe 2 O 3) titanium oxide (TiO 2) etc. b) Concentration is carried out by digesting powdered ore with a concentrated solution of sodium hydroxide at 473523 K and 35-36 bar pressure.
Chat Online· Raw iron ore mined from the Earth is the main ingredient but it first needs to be concentrated before it can be used to create steel. The blast furnaces at Volklinger Ironworks turned raw ore into pig iron using high heat coke and limestone to reduce oxygen and sulfur — producing a "slag" of impurities that floats to the top.
Chat OnlineHaematite ore being oxide ore is concentrated by gravity separation process using hydraulic separator. The oxide is being heavier settles to the bottom while lighter impurities come to
Chat OnlineInstead the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron. Wrought iron is hardy and easy to work making it perfect for creating tools.
Chat OnlineThis concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process that helps in separating the useful
Chat Online· Iron is concentrated by the process of calcinations. Once it is concentrated the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Chat Online· Conversion of ore into metal a) The less reactive metals are extracted by reduction of their oxides by heat alone. For Ex Copper and mercury 1)Ore of mercury is cinnabar Mercury oxide is reduced to mercury on heating. HgS(s) 3 O 2 (g) —–> 2 HgO (s) 2 SO 2 (g) 2 Hg(s) ——> 2 Hg(l) O 2 (g) 2)Ore of copper is copper glance
Chat Online· Pig Iron. To create usable pig iron from the raw material a blast furnace is fed with iron ore coke and small amounts of flux to collect impurities. The furnace is blasted with hot air at around 1200°C which causes the coke to burn producing carbon monoxide which reacts with the raw iron.
Chat OnlineConcentrated ore of iron coke and limestone are fed into a blast furnace from the top. i) Write down the reason for adding limestone along with the concentrated ore of iron. ii) Write down the reactions taking place at the higher temperature range in the blast furnace. OR . Metals are extracted from their chief ore.
Chat Online· The small pieces of ore are then changed into a fine powder with the help of a stamp mill or ball mill. The process is called pulverization of the ore. B) Dressing or Concentration of the Ore. Ores extracted from the earth s crust are not pure as it contains various unwanted impurities like sand rocky material earthy particles etc.
Chat Online· 1) It is the process by which a carbonate ore is heated strongly in the absence of air to convert into metal oxide. It is a process in which sulphide ore is heated in the presence of air to convert into metal oxide. 2) ZnCO3 —->ZnO CO2. 2ZnS—->2ZnO 2 SO2 3 O2.
Chat OnlineThe pig iron limestone and iron ore go into an open-hearth furnace. It is heated to about 1 600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities including carbon are oxidized and float out of the iron into the slag. When the carbon content is right you have carbon steel.

The most common process is the use of a blast furnace to produce pig iron which is about 92-94 iron and 3-5 carbon with smaller amounts of other elements. Pig iron has only limited uses and most of this iron goes on to a steel mill where it is converted into various
Chat OnlineIron ore usually ends up in blast furnaces and steel mills where it is turned into iron and steel through smelting and refining. Iron ore is smelted in blast furnaces to produce pig iron .
Chat Online· The host rock for the iron ore is the iron formation which during its long complicated geological history has been partially concentrated into isolated segments of ore of different shapes sizes and attitudes. The first step in prospecting for an ore body is to determine the continuity of the iron formation where it is at or near the surface by
Chat Online· Iron ore is an essential component for the global iron and steel industries. Almost 98 of mined iron ore is used in steel making. About 50 countries mine iron ore with Australia and Brazil
Chat OnlineThe following diagram shows how iron is extracted from iron ore in a blast furnace. Scroll down the page for more explanations on extraction of iron. of about 96 per cent iron with carbon and some other impurities. It is hard but too brittle for most uses. So most iron from the blast furnace is converted into steel by removing some of the
Chat Online2 days ago · Much of the ore is mined in Australia Brazil China India Russia and the US. Most ores contain more than 60 iron and are used in their mineral state in a blast furnace. Ore containing less than this is first crushed and ground into a powder and concentrated by flotation.
Chat OnlineIron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron one must deoxygenate the ore leaving only iron atoms behind which is the essence of the refining process.
Chat OnlineIron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose a traveling-grate machine is used and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.
Chat Online2 days ago · The ore concentration is defined as the chemical process of eliminating impurities like sand rocks silt grit etc. from the ore to extract the metals. In simple words the concentration of ore is the method of separating ore from the gangue as the gangue or matrix particles are the valueless substances that are of no use.
