Extraction of Iron Metallurgy Blast Furnace and Reactions

How is iron extracted from its ore? It’s a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. 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.

Ironmaking 101 – From Ore to Iron with Blast Furnaces ...

Oct 10, 2017  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. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used

Processes and Procedures in the Extraction of Iron ...

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.

Blast Furnace Process - an overview ScienceDirect Topics

Jan 01, 2010  The blast furnace process is primarily used in the carbothermic reduction of oxides, such as iron, zinc, and lead. Most of the iron ore bodies commercially explored consist of iron oxides. Consequently, rich iron ore and/or iron oxide pellets formed from concentrate can be added directly to a blast furnace (see Iron Production).

As an alternative to iron production in a blast furnace, direct-reduced iron (DRI) is produced by reducing iron ore using a mixture of hydrogen and carbon monoxide (Reaction (5.7) and (5.9)) at temperatures of 800–1000°C. The first commercial CCS project at a steel plant began operating in November 2016 at the Emirates Steel DRI plant in Mussafah, Abu Dhabi.
