OREAS 990b
رمز المنتج: 990b
OREAS 990b is a copper-gold-silver concentrate certified reference material
(CRM) sourced from the Rosebery metallurgical plant owned and operated by MMG
Ltd. The Rosebery mine and plant are located in the north-west region of
Tasmania, Australia approximately 300 kilometres north-west of Hobart and 125
kilometres south of Burnie. The key minerals of economic importance include
sphalerite, galena, pyrite, chalcopyrite and electrum. Fifteen ‘umpire’
laboratories undertook copper, gold, silver and moisture analysis on the sample
as received but the results are corrected to a dry sample basis. The term
‘umpire’ here refers to the routine analysis by these laboratories using
classical methodologies for precious and base metals. Fifteen geoanalytical
laboratories also participated in the program to undertake the following:
Full elemental suites by peroxide fusion with ICP-OES and MS finish;
Full elemental suites by 4-acid digestion with ICP-OES and MS finish;
Total S by IR combustion furnace;
Gold by instrumental neutron activation analysis (INAA) to confirm
homogeneity (undertaken by ANSTO, Lucas Heights).
