Petrogenetic characterization of the host rocks of the Sanaga iron ore
The Sanaga iron ore prospect is a recent discovery in the Nyong Series with a resource estimated at 82.9 Mt at 32.1% Fe and whose origin remains debatable. The mineralization occurs as NE-SW oriented discontinuous lenticular bodies of magnetite-bearing pyroxene-gneisses (MPG) hosted by ortho-derived gneisses. Rare amphibolites Currently, most mining companies conduct chemical analyses by X-ray fluorescence performed in the laboratory to evaluate the quality of Fe ore, where the focus is mainly on the Fe content and the presence of impurities. However, this type of analysis requires the investment of time and money, and the results are often available only after AI Free Full-Text Monitoring of Iron Ore Quality through

Magmatic origin of giant ‘Kiruna-type’ apatite-iron-oxide
Iron is the most important metal for modern industry and Sweden is by far the largest iron-producer in Europe, yet the genesis of Sweden's main iron-source, the ‘Kiruna-type’ apatite-ironIntroduction. China is characterized by the world’s largest demand for iron ores and more than 50% of this demand is met by foreign sources (1.31 billion tons iron ores with the grade in the range 20–30% TFe from domestic and 0.74 billion tons iron ores with the grade >50% TFe from abroad in 2012).Li et al.

Automated optical image analysis of natural and sintered iron ore
Automated optical image analysis (OIA) is a relatively cheap, robust, and objective method for mineral and textural characterization of iron ores and sinters. OIA allows reliable and consistent identification of different iron oxide and oxyhydroxide minerals, e.g., hematite, kenomagnetite, hydrohematite, and vitreous and ochreous goethite, andof raw iron ore fines had became the hot topic in the sintering production [9−10]. Other factors, including SiO2 [11], Al2O3 and MgO [12] contents in raw materials, have also been considered. With respect to the iron ore sintering, calcium ferrite is generated between the iron ore and flux particles at high temperature. Therefore,Calcium ferrite formation characteristic during iron ore
