Abstract

The application of Raman spectroscopy, utilizing a HyLogging™ automated core-scanning platform, to map the iron ore and gangue mineralogy in banded iron formation drill core and hematite-rich, detrital iron deposit ore was tested as a demonstration of the potential of this technique for rapid, in situ mineralogical mapping. The common iron ore Fe-oxide mineral hematite as well as gangue minerals, such as quartz and Fe²⁺-carbonate, shows distinct Raman spectra, which enabled these phases to be readily detected and mapped in situ. Despite also exhibiting a distinct Raman spectrum, detection of magnetite was problematic and is now the focus of ongoing research to optimize the Raman scanning conditions to enhance detection of the common iron ore and BIF mineralogy.

Coupling to the HyLogger™ platform clearly extends and augments the utility of Raman spectroscopy for routine characterization of iron ore mineralogy and delivers a step change to current characterization methods that underpin strategies to best manage and process existing Australian iron ores (e.g., BID and CID), as well as the newly developed MID ores.
