After extraction, iron ore is processed to remove impurities and obtain the desired iron content through crushing, grinding, magnetic separation, and other beneficiation techniques. ... In summary, iron ore is a crucial raw material for the production of iron and steel, with significant global demand and supply dynamics, and …

Use washing to remove very fine harmful particles. Washing of run-of-mine ore can be carried out to facilitate sorting by removing obscuring dirt from the surfaces of the ore particles. However, washing to remove very fine material, or slimes, of little or no value, is more important. Washing is normally performed after primary crushing as the ...

Here are a few important types of iron ore (the first three are the main types): (1) Magnetite is an iron oxide ore with the primary composition of Fe3O4, a compound of Fe2O3 and FeO. It is blackish-grey, with a specific gravity of about 5.15, containing 72.4% Fe and 27.6% O. It is magnetic and can be conveniently processed by magnetic ...

1. Introduction. In general, since more than 90% of iron ore is used as the raw material to produce iron and steel, the composition of iron ore and the basicity of blast furnace slag for the production of clean and high purity steel have been the focus of recent studies (Gan et al., 2012, Dwarapudi et al., 2014).After the iron making process, the …
