Regarding Brazilian iron ore processing plants, the typical flotation feed consists of particles in the size range between 10 µm and 300 µm and the desliming process is carried out by hydrocyclones [16]; thus, the Fe content in the Brazilian slimes is high in comparison to the slimes produced by the selective flocculation process.

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
