OREAS 903
Артикул: 903
OREAS 903 contains 93 certified values and is a medium grade
transitional-oxide copper ore certified reference material. It is one of a suite
of four transitional to oxide copper (-gold) CRMs prepared from samples
sourced from CST’s Lady Annie Mine, located 120 kms northwest of Mount Isa,
Queensland, Australia. Mineralisation at Lady Annie is hosted in dolomitic,
carbonaceous and argillaceous sandstones and siltstones. The primary copper
sulphide mineralisation at depth is dominated by chalcocite and chalcopyrite and
appears to be structurally controlled, being commonly associated with
fault-related silicification.
Nineteen commercial analytical laboratories participated in the program. The
following methods were employed:
Four acid digestion with ICP-OES and ICP-MS finish (46 certified values)
Aqua regia digestion with ICP-OES and ICP-MS finish (46 certified values)
Soluble Cu via 5% H2SO4 acid leach with AAS or
ICP-OES finish
Gold via fire assay with ICP-OES, ICP-MS, AAS or solvent extraction AAS
finish
