This project combines two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget.

This project combines two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget.
The first discipline is ore geology; the object is to describe the mineralogy and chemical variations of different ore bodies and ore types but also to characterise the mineral chemistry of the ore minerals. By understanding the metamorphic influence, particular the chemical and textural effect on the ore minerals this study could also contribute to the controversial discussion of the origin of the apatite iron ore (Kiruna type). The second discipline is process mineralogy; the object is to characterise the ore minerals, its ability of liberation, the mineral associations and textures but also to identify specific mineral associations, common for a certain type of ore body and ore type. These mineral associations could act as a signature and create traceability in the process chain during the concentration. By improving the mineralogical understanding of the minerals and their textures, a certain process problem of mineralogical character could be identified and solved.
