Cost savings are realized from reduced preparation and analytical time, labor cost reduction, and lack of reagent consumption when compared to fire assay analysis. Examples from one mine demonstrate preparation and analysis time can be reduced from 2 hours using traditional fire assay methods to 2 minutes using handheld XRF.
