Iron Ore Sinter an overview ScienceDirect Topics

L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.5 Conclusions. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.

Sinter plant Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

Blast furnace Wikipedia

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and
