Abstract [en]

Mineralogical information forms an essential basis in geometallurgy. Minimum information required in a mineralogical approach of a geometallurgical program is: modal mineralogy (mineral quantities) and mineral textures. Based on this information it is possible to link geological model with production model. Modal analysis is currently mostly done with Scanning Electron Microscopy (SEM) based image analysis, often called as automated mineralogy. As this method is tedious, slow, and costly, and has some limitation, an alternative technique was developed by combining quantitative X-ray diffraction (XRD) and chemical assays by X-ray fluorescence (XRF). In iron ores in Northern Sweden combined method gives a quantity of about ten minerals with adequate accuracy.
