role of coke in extraction of iron

Sep 09 2018 · Actually coke is a form of carbon that is “purified” by removing most of the organic compounds sulfur compounds and heavy metals from coal Coke is a reducing agent and in a blast furnace at high temperature coke is capable of reducing iron oxide Fe2O3 or FeO to metallic iron reference The Blast Furnace 13K views

Iron ore is not normally smelted instead it is reduced in a blast furnace with a mixture of coke limestone The coke burns removing the oxygen from the iron ore and melting the resulting iron

Coke is a black powdery substance It is used as a reducing agent The concentrated ore is reduced in a blast furnace with different reactions in different regions

Jul 13 2018 · Carbon seems to play a significant role in influencing the brittleness and hardness balance in iron To further reduce the carbon content of pig iron it is melted again with scraps of iron and coke and subjected to the blast of hot air This kind of iron is called Cast Iron and has a slightly lower carbon content 2 – 3

It is called pig iron Pig iron is melted with scrap iron and coke in the presence of hot air to form cast iron which contains only 3 carbon Cast iron is heated in a reverberatory furnace lined with haematite which oxidises carbon to carbon monoxide to get wrought iron or malleable iron the purest form of iron Fe 2 O 3 3C → 2Fe 3CO

of iron ore extraction 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 which supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron How nut coke is charged in blast furnace nut coke is charged in blast furnace with the

Iron is extracted from its ore haematite in a blast furnace The ore is fed into the top of the furnace along with coke and limestone The limestone decomposes in the hot furnace forming calcium oxide This reacts with the sandy impurities silicon dioxide to form a slag Archana

Extraction of iron is based on the reduction of HAEMATITE Fe 2 O 3 As the CO 2 passes upwards it reacts more coke to form carbon monoxide CO 2 C 2CO heat Formation of CO is an endothermic reaction and the temperature in this region falls to 1100 O C CO is the main reducing agent in the upper portion of blast furnace

Sep 23 2019 · Coke is cheap and it provides both the reducing agent and heat source for the reaction The most commonly used iron ores are Hematite Fe2O3 and magnetite Fe 3 O 4 The process of extraction of iron and their separation is followed by three major steps Concentration of Ore Extraction of Iron from its concentrated ore Purification of Iron

Iron ore is produced in around 30 countries – in 2017 the largest producers were Australia Brazil and China Around 98 of iron ore is used in steelmaking During the ironmaking process a blast furnace is fed with the iron ore coke and small quantities of fluxes minerals such as limestone which are used to collect impurities

Extraction of Iron Metallurgy Blast Furnace and This 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 components from the

of iron ore extraction 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 As a leading global manufacturer of crushing equipment milling equipmentdressing equipmentdrying equipment and briquette equipment etc we

the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron

2a Extraction of Iron in a blast furnace Sadly now shut down Raw Materials Iron Ore eg haematite ore ironIII oxide the source of iron Fe 2 O 3 or magnetite ore Fe 3 O 4 coke carbon C both fuel and reducing agent hot air for the oxygen in it to burn the coke O 2 limestone calcium carbonate to remove certain impurities like silica

i Zone refining method is the most suitable method for refining metals like germanium semiconductor ii In the extraction of aluminium impure Al2O3 is dissolved in concentrated NaOH to form method is known as leaching of alumina iii Coke reduces the iron oxide to molten iron metal Also coke when burnt in the blast furnace supplies the heat required for carrying out

in a huge container called a blast furnace Iron ores such as haematite contain ironIII oxide Fe 2 O oxygen must be removed from the ironIII oxide in order to leave the iron behind

Oct 23 2018 · Iron 26 Fe 18 Ar 4S 2 3d 6 is found in the earth’s crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica SiO 2 Al 2 O 3 CaO and MgO and some harmful impurities such as s p and As The suitability of the ore in the extraction of iron economically depends on three factors which are

Which of the following slags is produced during extraction of iron A When the ore hermatite is burnt in air with coke around 2 0 0 0 K along with lime the process not only produces steel but also produces a silicate slag that is useful in making building materials such as cement Discuss the same and show through balanced chemical equations
