process of low grade iron ore in steel mills

This is how iron ore is turned into steel

2017-11-1  Electric Arc Furnace (EAF) mills use steel scrap rather than iron ore as the main raw material input, and require a smaller initial investment versus the more capital-intensive blast furnace process.

12.5 Iron And Steel Production

2015-9-10  The sintering process converts fine-sized raw materials, including iron ore, coke breeze,limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charginginto the blast furnace. The raw materials are sometimes mixed with water to provide a cohesivematrix, and then placed on a continuous, travelling grate called the sinter strand. A burner hood, atthe beginning of the sinter strand ignites the coke in the mixture, after which the combustion is selfsupporting and it provides sufficient heat, 1300 to 1480°C (2400 to 2700°F), to cause surface meltingand agglomeration of the mix. On the underside of the sinter strand is a series of windboxes that drawcombusted air down through the material bed into a common duct, leading to a gas cleaning device.The fused sinter is discharged at the end of the sinter strand, where it is crushed and screened.Undersize sinter is recycled to the mixing mill and back to the strand. The remaining sinter

2021-8-22  The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural iron-bearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore. By definition, steel is a combination of iron
