OREAS 752b

OREAS 752b has been prepared from a blend of spodumene concentrate derived from the processing of lithium pegmatite ores sourced from the Greenbushes area of southwest Western Australia, Londonderry lithium-pegmatite ore (containing elevated levels of lithium, rubidium, cesium, tin and tantalum), barren granodiorite and quartz. The barren granodiorite was sourced from the mafic, S-Type, Late Devonian Bulla Granodiorite complex located in northern Melbourne, Australia. The Certification Program will include:

  • Sodium peroxide fusion with full suite elemental package by ICP-OES and/or MS finish
  • Lithium borate fusion whole rock analysis package by X-ray fluorescence
  • Thermogravimetry: Loss on Ignition (LOI) at 1000°C
  • 4-acid digestion for full suite elemental package by ICP-OES and MS finish
