OREAS 112
رمز المنتج: 112
OREAS 112 is a high grade Cu ore certified reference material (CRM) prepared
from material sourced from the Tritton Copper Project near Nyngan, New South
Wales. The deposit consists of sulphide ore bodies (massive pyrite and
chalcopyrite breccias) underlying oxide ores. OREAS 112 is one of a suite of
five CRMs and was prepared from massive pyrite material blended with
chalcopyrite breccia ore. All five CRMs have been characterised for Ag, As, Cd,
Co, Cu, Fe, Pb, Sb and Zn by 4-acid ICP and sodium peroxide fusion ICP
methods.
