摘要

The value of Raman spectroscopy to undertake mineral and chemical characterisation of ironrnores was assessed by applying the technique to representative samples of banded iron-formationsrn(BIF) and a BIF-derived, martite-goethite ore. The common iron oxides haematite, magnetite andrngoethite as well as gangue minerals such as quartz and carbonates all show distinct Raman spectrarnthat enables these phases to be easily detected and mapped in situ for either samples preparedrnas polished blocks or unprepared material. Raman spectroscopy also offers the potential of inrnsitu chemical characterisation. Shifts in the excitation bands of carbonate detected in BIF werernrelated to the Mg content of Fe-carbonate and confi rmed the fi rst world-wide occurrence of a highrnMg-bearing siderite (pistomesite) in BIF.rnThe discriminatory power of Raman spectroscopy coupled with the potential of the techniquernto offer large-scale (volumetric) characterisation of iron ore will be of great value not only to thernexisting BID and CID ore types, but also to the newly emerging magnetite iron deposits (MID).
