OREAS 505b
Артикул: 505b
OREAS 505b is a porphyry Cu-Au certified reference material prepared from a
blend of ores, barren granodiorite and minor additions of copper and molybdenum
concentrates. The ores were predominantly sourced from Northparkes Mines (NSW,
Australia) blended with lesser quantities of other porphyry ores from Australia
and Papua New Guinea. The barren granodiorite was sourced from the mafic,
S-Type, Late Devonian Bulla Granodiorite complex located in northern Melbourne,
Australia. Thirty-one commercial analytical laboratories participated in the
program to certify the elements reported below.
Gold by fire assay (15-50g charge weight) with ICP-OES, ICP-MS or
AAS finish
Gold by aqua regia digestion (10-50g sample weight) with ICP-OES,
ICP-MS or AAS finish
Full ICP-OES and ICP-MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl)
digestion
Full ICP-OES and ICP-MS elemental suites by aqua regia digestion
Instrumental neutron activation analysis for Au on 20 x 85mg subsamples was
also undertaken at ANSTO, Lucas Heights to confirm
homogeneity.
