Abstract

Mössbauer spectroscopy has been used to study nine natural chromite samples from deposits throughout Brazil and one sample from Philippine. It was possible to identify three different groups of chromite spinels, depending on the iron distribution over tetrahedral and octahedral sites. Using the Mössbauer Fe3+/Fe2+ ratio, chemical analysis and x-ray data a chemical formula was proposed for each group.
