Iron ore beneficiation is the process of increasing the concentration of iron in the ore to improve its quality and make it more suitable for steel production. This process typically involves physical methods such as flotation, magnetic separation, and gravity separation to remove impurities and enhance the iron content. Beneficiation is crucial because higher quality iron ore can ...

Iron ore is a valuable commodity used for steel manufacturing, which is a key part of the modern economy (Lu 2015). Today, banded iron formations are an important source of iron ore for mineral extraction (M.I.I. n.d.). The iron bearing minerals typically mined from such deposits are magnetite and hematite [Klemic et al. 1973]. The iron
