OREAS 994
OREAS 994 was prepared from a blend of copper concentrate laboratory reject
samples sourced from several Australian mine site metallurgical plants. Copper,
Iron and Sulphur by weight account for 82.5% of the total chemical composition
of OREAS 994.
Fifteen ‘umpire’ laboratories undertook copper, silver and
moisture analysis on the sample as received. 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 analytical 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.
