A pressing issue that has often been the topic of discussion in iron-making operations in India is the high content of alumina in the country's iron ore deposits. The presence of alumina has hampered production by affecting slag fluidity, and thereby the hot metal quality. Iron ores from Indian mines are generally rich in hematite, with traces or small amounts of goethite/limonite, kaolinite ...

Mar 19, 2022This study aims to estimate the content of SiO 2 and TFe in iron ore tailings based on visible-near infrared (VIS-NIR, 350-2500 nm) and thermal infrared (TIR, 8-14 μm) spectroscopy. The outer product analysis (OPA) method is used to combine VIS-NIR and TIR spectral domains, from which an outer product matrix of fusion data can be generated.
