2019-6-18 It’s a major ingredient in steel. Here’s what the USGS has to say about iron ore: Iron ore is the source of primary iron for the world’s iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore

portion of −20 ˚m in iron ore concentrate favoured the granulation and the productivity in conventional sintering, but the portion of +45 ˚m had the reverse effects. With increases in finer commercial concentrates (10–40 mass%) combined with low grade ore (10–20 mass%) in iron ore blends, the productivity also did not obviously change.

iron ore concentrate contains a lower alumina. Recently it is more popular to be applied in commercial sinter plants to decrease the alumina content in sinter or combined with a high alumina low grade ore to reduce the production cost of sintering. However the productivity of sinter decreased with a decrease in the size of iron ore.
