chromite ores. For example, assuming that a chromitite ore consists essentially of chromite with density of approximately 4.5 g/mL and pyroxene with density around 3.3 g/mL, it should be possible to estimate bulk density based on XRF 'whole rock' analyses. A further example may be impure barite ore, in which
