Zetium - Analysis of phosphates using the WROXI widerange oxides application

This data sheet demonstrates the performance of the Zetium - Minerals edition XRF spectrometer in providing accurate and precise phosphate analyses.

Phosphates occur as massive sediment-hosted phosphate rock, or as apatite minerals in igneous and metamorphic rocks. They are normally processed through phosphoric acid and super phosphoric acid intermediates to make ammonium phosphate fertilizers and elemental phosphorous. The presence of Fe2O3, Al2O3 and SiO2 need to be monitored because these affect the conversion of phosphates to super phosphoric acid.
