What Is Iron Ore Sintering? (with pictures)
2020-2-22 Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.

Iron ore sintering is an important pre-processing technol-ogy in integrated steel mills. Sinter accounts for around 70 wt.% of the ferrous feed to blast furnaces in the Asia-Pacific region.1) Sinter making is a complex process and can be viewed as comprising bed preparation under ambient con-ditions (or cold processing) and subjecting the bed to high temperatures by generating a narrow, moving

Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 % of the total global iron ore mining volume.
