Consequently rich iron ore andor iron oxide pellets formed from concentrate can be added directly to a blast furnace see Iron Production In the case of zinc and lead their ores are sulfidic Therefore before the carbothermic reduction can take place the zinc and lead sulfide concentrates are converted to oxides and agglomerated
The equation for the reaction of iron ore in a blast furnace is given below Fe 2 O 3 3CO 2Fe 3CO 2 How many kilograms of iron can be produced by the reaction of 700 kg of Fe 2 O 3 and 300 kg of CO Atomic weight Fe 5585 O 1600 C 1201

Extracting iron from iron ore using a Blast Furnace The common ores of iron are both iron oxides and these can be reduced to iron by heating them with carbon in the form of coke Coke is produced by heating coal in the absence of air Coke is cheap and provides both the reducing agent for the reaction and also the heat source
Oct 10 2017 In the upper region of the blast furnace where temperature range from 600 to 700 C the iron ore or iron oxide is reacts with the gaseous CO reductant to produce iron Fe 2 O 3 s 3COg 2Fe 3CO 2 g Lower in the blast furnace where higher temperatures occur the iron ore may react directly with the coke or carbon
In the blast furnace it is so hot that carbon monoxide can be used in place of carbon to reduce the ironIII oxide ironIII oxide carbon monoxide iron carbon dioxide Fe 2 O 3 s
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore and the conversion of the raw iron from the furnace into various kinds of steel The common ores of iron are both iron oxides and these can be reduced to iron by heating them with carbon in the form of coke
Jun 13 2014 Iron ore pellet can be used as a substitute to sinter and calibrated lump ore in the blast furnace burden due to the following properties Spherical shape and open pores of pellets gives better and uniform permeability resulting in smoother furnace operation Pellets have a uniform size range generally within a range of 8 20 mm
31 blast furnace pig iron 1 However an attractive feature of DR compared to blast furnace reduction 32 is its much lower CO2 emissions which are 40 to 60 lower for the DRelectric arc furnace route 33 compared to the blast furnacebasic oxygen furnace route 2 Among the DR processes the shaft
Direct reduction refers to solidstate processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron Reduced iron derives its name from these processes one example being heating iron ore in a furnace at a high temperature of 800 to 1200 C 1470 to 2190 F in the presence of the reducing gas syngas a mixture of hydrogen and carbon monoxide
Comparing these with the ordinary blast furnace reaction which requires 9C put into the furnace for the reduction of Fe20 we see that 3C or onethird as much carbon is the amount necessary in the electric furnace reduction and 2C or between onethird and onefifth as much is the smallest amount necessary
The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue The iron found in iron ores are found in the form of iron oxides
Indirect reduction is the production of steel from iron ore in two steps first adding carbon then removing carbon Note Numerous details have been left out for the sake of clarity The information below is not sufficient for the production of highquality metal
A further lowering of the iron ores in the blast furnace leads to the temperature zone of 400 C to 800 C In this region the socalled indirect reduction of iron ores to iron by carbon monoxide takes place
In the blast furnace it is so hot that carbon monoxide can be used in place of carbon to reduce the ironIII oxide ironIII oxide carbon monoxide iron carbon dioxide Fe2O3s
Oct 19 2009 What is the word equation for the reduction of iron ore with reaction reduction with carbon in a blast furnace at temperatures of about 2000 C equation below hematite to molten iron
Aug 30 2009 The carbon monoxide reduces the iron ore whether hematite or magnetite ore is used as shown below to molten iron becoming carbon dioxide in the process Fe2O3 3CO 2 Fe 3 CO2 Fe3O4 4 CO 3 Fe 4 CO2 The flux is present to melt impurities in the ore principally silicon dioxide sand and other silicates
The following equation shows sodium losing the electron For example iron ore primarily rust is reduced to iron metal in a blast furnace by a reaction with carbon monoxide The iron has lost oxygen so chemists say that the iron ion has been reduced to iron metal
Oct 19 2009 The symbol equation for the reduction of iron ore with carbon monoxide is Fe2O3 3CO 2Fe 3CO2 Iron is extracted from its oxide ores primarily hematite by
Aug 26 2014 The symbol equation for the reduction of iron ore with carbon monoxide is Fe2O3 3CO 2Fe 3CO2 Iron is extracted from its oxide ores primarily hematite by
