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 main reducing agent is carbon monoxide: iron(III) oxide + carbon monoxide iron + carbon dioxide The molten iron is then tapped from the bottom of the furnace...
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use In this chapter, the sintering process is first described and the key steps of the sintering process, namely, granulation and thermal densification, are identified...
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue" The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent...
Iron ore pelletizing systems Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets These are typically fed to a blast furnace or DRI plant as part of the process to make steel...
Evolution of Blast Furnace Iron Making , as obtained from red iron ore Developments in iron making process Improvements in this first iron making process were made by lining the smelting hole with stones as well as mud and using bellows made of wood and leather (Fig 2) In China, the use of iron appeared about 600 BCE, spreading widely ....
