OREAS 751b
SKU: 751b
OREAS 751b 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 includes:
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
