| Popis: | Magnetite ore has increasingly become an important component in the raw material mix for steel production. South Australia has estimated 14 billion tonnes of untapped magnetite reserves. The present study investigates the chemical and mineralogical characteristics of a selected magnetite ore from South Australia. X-ray florescence (XRF), quantitative X-ray powder diffraction (XRD), and Quantitative Evaluation of Minerals by Scanning Microscopy (QEMSCAN) were used to identify and characterise magnetite and its associations. MAGNASAT Magnetic Susceptibility meter was used to study and confirm the magnetic properties of magnetite by measuring the magnetic susceptibility of differing size fractions of the ore.Mineralogical studies identified magnetite as the dominant iron-bearing mineral, with minor hematite and goethite associations, whereas quartz was identified as the major gangue mineral. A direct relation between magnetic susceptibility and magnetite mineral abundance in the various size fractions was observed. Magnetite mineral is concentrated in the -75 +45 µm size fractions |
