Abstract
Abstract A range of techniques has been applied to the mineralogical and microchemical characterization of high-grade iron ore hosted by banded iron formation (BIF), including reflectance spectroscopy, X-ray diffraction, Raman spectroscopy, scanning electron microscope, electron microprobe, and proton induced X-ray emission analysis (PIXE). These tools provide key physicochemical properties of the main ore minerals, such as magnetite, kenomagnetite, maghemite, hematite, and goethite, which in turn determine the grade of the deposit and its economic viability. For instance, current automated HyLogging™ systems, based on reflectance spectroscopy, provide quick and objective m..
