basic pig iron: used mainly in electric arc steelmaking; foundry pig iron (also known as haematite pig iron): used in mainly in the manufacture of grey iron castings in cupola furnaces; high purity pig iron (also known as nodular pig iron): used in the manufacture of ductile [also known as nodular or spheroidal graphite – SG] iron castingsSep 01, 2020 Pig iron for the manufacture of steel accounts for 98% of all iron ore production, with about 16 tonnes of the material needed to manufacture one tonne of the alloy Comprising nearly 5% of the earth’s crust, iron ore is mostly found in the form of haematite (which gives out the reddish tint in iron ore) and magnetite (lodestone)Top five iron ore producing companies of the worldThe reactions during manufacture of steel are Mixture of cast iron scrap iron , haematite and small amount of lime is kept on hearth of open hearth furnace mixture is healed by burning producer gas by regenerative system The outgoing hearth gas pre Heats the incoming producer gas which an combustion can generate higher temperatureManufacture of Steel Reference Notes Grade 12 Science It is mined as the main ore of iron Hematite is the world’s most important ore of iron Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world Hematite is a highdensity weighting materialHematite Powder ISHTAR COMPANY LLCIron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks The iron content of these ores ranges from 70% down to 20% or less Coke is a substance made by heating coal until it becomes almost pure carbonHow iron is made material, manufacture, making, history

Why limestone is used in the manufacture of pig iron from
Why limestone is used in the manufacture of pig iron from haematite Dear Student Lime stone ( CaCO 3 ) when added to molten iron it decomposes into CO 2 and C(i) Role of limestone in the manufacture of pig iron from haematite The limestone decomposes in the hot furnace, forming calcium oxide This reacts with the sandy impurities (silicon dioxide) to form a slag hence limestone is added to the blast furnace CaCO₃ > CaO + CO₂ (ii) Role of Pine oil in the froth flotation process(i) Role of limestone in the manufacture of pig iron from 2c NOTE on RECYCLING Iron and Steel About 42% of iron/steel in goods/components manufactured in iron/steel is recycled iron/steel, whether it be steel pans, car bodies, bridge girders, stainless steel cutlery etc; This makes good economics because recycling saves on several costs AND allows a mineral resource like iron's haematite or magnetite ore resources to last a lot longer – slower gcse 2 Blast furnace extraction of iron recycling, steel (i) Role of limestone in the manufacture of pig iron from haematite The limestone decomposes in the hot furnace, forming calcium oxide This reacts with the sandy impurities (silicon dioxide) to form a slag hence limestone is added to the blast furnace CaCO₃ > CaO + CO₂ (ii) Role of Pine oil in the froth flotation process(i) Role of limestone in the manufacture of pig iron from It is mined as the main ore of iron Hematite is the world’s most important ore of iron Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world Hematite is a highdensity weighting materialHematite Powder ISHTAR COMPANY LLC

This kind of iron is called Cast Iron and has a slightly lower carbon content 2 – 3 % This is even harder than pig iron Wrought Iron/ Malleable Iron Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe2O3)Iron is the second most abundant metal occurring in the earth’s crust It is an element of the first transition series OCCURRENCE The important ores of iron are: 1 Haematite, Fe 2 O 3 (red oxide of iron) 2 Magnetite, Fe 3 O 4 (magnetic oxide of iron) 3 Limonite, Fe 2 O 33H 2 0 (hydrated oxide of iron508 EXTRACTION OF IRON Chemistry AssignmentA blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper Blast refers to the combustion air being "forced" or supplied above atmospheric pressure In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with Blast furnace WikipediaUses: Magnetite iron is used as natural magnets and in electrical industry Haematite (Fe 2 O3): (Iron content 70%) Most important iron ore They are red ores derived from sedimentary rocks and occur in crystalline or in powdery forms Haematite iron is most important for the purpose of industrial useWhat are the Important Characteristics of Iron ore?28 Which raw materials are used in the manufacture of iron?
