Agglomeration of iron concentrate powder and rich iron ore powder is realized by iron ore sintering and pelletizing. (1) In iron ore sintering, the iron ore powder, flux, fuel, substitute material, and return fines are made into a mixture with a certain mix ratio, into which an appropriate amount of water is added. After mixing and …

Sintering and pelletizing are iron ore agglomeration processes that allow the use of ores with a size lower than 10 mm in the blast furnace, without impairing the furnace's permeability (Fernández-González et al., 2017a). Sintering is the most widely used agglomeration process in the world for ferrous burden preparation to the blast …
