The concentration of low-grade iron ores is vital to the continued availability of iron and steel in our everyday lives (Eisele and Kawatra, 2003;Kawatra and Claremboux, 2021a;Zhang et al., 2021).
Blast furnaces use most of the iron ore mined today, but greener, more sustainable technologies are gaining ground – and they bring a demand for ore-based products with …
Making iron and steel from iron ore requires a long process of mining, crushing, separating, concentrating, mixing, agglomeration (sintering and pelletizing), …
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents and solid fuel (coke).
Moreover, the conventional iron making unit, i.e. blast furnace requires the raw material in the form of iron oxide with a size range of 10–120 mm. Sintering is the oldest agglomerate thermal process using iron ore mineral fines of 0.5–8 mm, along with the reductant, fluxes, and other byproducts of the iron and steel industry operated ...
