OREAS WON25 P2O5 (24.70 wt.%) phosphatic limestone

Item: ORWON25_10g

Unit of measure: ea

Description:

WON25 was prepared from phosphate ore sourced from the Wonarah Phosphate Project located in the Barkly Tableland of Northern Territory, Australia. The project consists of two sites known as ‘Arruwurra’ and ‘Main Zone’. WON14 is one from a suite of four phosphate CRMs (the others being WON20, WON25 and WON30). All four CRMs have been characterised for P2O5, SiO2, TiO2, Al2O3, Fe2O3, CaO, MgO, MnO, K2O, Na2O and LOI at 1000°C.
