Abstract [en]

This study was an attempt to find a way of characterising an iron ore body both mineralogical and textural in a quantitative manner by using analytical methods like optical microscopy, microprobe (EMPA) and an automatic SEM based system, Particle Texture Analysis (PTA). The source of this study is an iron ore body, called Fabian, located in Malmberget, Sweden. Two types of ores were identified and analysed in this study named "orebreccia" and "ore". The Particle Texture Analysis was made on two fractions of crushed ore. The mineralogy was evaluated and characterized as mineral liberation and mineral association. Magnetite has a simple outline and straight grain boundaries and the gangue minerals have a finer particle size with a more complicated texture. The liberation of magnetite in "ore" and "ore breccia" is high. The ore quality for both "ore" and "ore breccia" does have similarities in a process technique perspective.
