OREAS 501e
Артикул: 501e
OREAS 501e was prepared from a blend of porphyry copper-gold ores, barren
granodiorite and minor quantities of Cu and Mo concentrates. The ores were
sourced from both the Ridgeway Mine and Northparkes Mine. Both mines are located
in the Central West of New South Wales, Australia. The barren granodiorite was
sourced from the mafic, S-Type, Late Devonian Bulla Granodiorite complex located
in northern Melbourne, Australia. Twenty-eight commercial analytical
laboratories participated in the program to certify the following:
Gold by fire assay using a 25-50 g charge weight with AAS (12
laboratories), ICP-OES (10 laboratories) or ICP-MS (1 laboratory) finish;
Gold by aqua regia digestion using a 10-50 g sample mass with ICP-OES/MS
(15 laboratories) or AAS (5 laboratories) finish;
Full ICP-OES and MS elemental suites by 4-acid digestion (up to 26
laboratories depending on the element);
Full ICP-OES and MS elemental suites by aqua regia digestion (up to 26
laboratories depending on the element).
To evaluate homogeneity, instrumental neutron activation analysis (INAA) of
Au on 20 x 1 g subsamples was undertaken at Actlabs Ancaster in
Canada.
