Among options to address this issue is a significant switch in iron ore mining focus from hematite towards magnetite. Magnetite ores tend to have a much lower Fe content but are often suitable for significant beneficiation, in part because magnetite is magnetic, enabling easier separation.

Hematite also has a high intensity band in the high wavenumber region. Because magnetite does not have Raman scattering in this wavenumber region, this Raman response can be used to distinguish these two oxides. The 1320 cm -1 band changes with changing magnetite/hematite ratios are presented in figure 3. Figure 3.

Iron ore | BHP
Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.

Hematite
No evolution of the spectrum was observed after the treatment of hematite by water, ruling out the hypothesis of Onoda and De Bruyn [7], as the formation of several layers of goethite should be detectable by this surface technique.However, a slow step was detected in our acid-base titrations of hematite (see section 3.1.) as observed by Onoda and De Bruyn [7].

Iron Ore Mining | Techniques | Metal Extraction
The iron by its own is usually found in the structure of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite. Hematite is also identified as "natural ore". The nomenclature dates back to the early years of drawing out, when certain hematite ores comprised 66% iron and could be fed reliably into iron edifice blast furnaces.
