process of iron ore coke and limestone

process of iron ore coke and limestone

Iron ore isn't pure iron oxide – it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone …

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. The extraction of iron from its ore is a very long and forlorn process that separates the useful components from the waste materials such as …

Iron. During the iron-making 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). Air which is heated to about 1200°C is blown into the furnace through nozzles in the lower section. The air causes the coke to burn, producing carbon monoxide

Jul 07, 2017 · Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight

Iron ore is primarily mined and refined through a process called smelting. Smelting is a heating process in which the Iron ore is heated along with coke (charcoal) and limestone in a blast furnace. The heating process melts the iron contained in the mixture and eliminates much of the carbon that is contained. Using variations of this process

Coke Limestone Iron Ore. The Iron Ore is first mined and then brought to the Blast Furnace. It contains impurities which have to be removed. Haematite (Hematite) and Magnetite are the most common ores. It takes about two tons of Iron Ore to produce one ton of iron, but this varies with different types of ores. Coke. Coke is made by heating soft

Feb 15, 2021 · The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres

Oct 10, 2017 · Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace.. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities
