The oxidizing borate fusion method (XRF76) is suitable for mineralized samples with sulphides, metal concentrates, metallurgical samples as well as ferro alloys, with the exception of FeSi. The default oxidizer is NaNO3, some sites offer LiNO3 to enable Na2O reporting. Please contact your SGS customer service agent.
Chromite ore XRF is the most recognized form of analysis for chromite ores in a high dilution borate fusion set up and is used throughout the mining lifecycle.
