OREAS 84

Ni–Cu–Co–PGE Ore

OREAS 84 was prepared from a blend of high-grade, komatiite-hosted nickel-copper-cobalt sulphide ores sourced from the Leinster district, Western Australia, supplemented with PGE-bearing Merensky Reef ore and Cr-rich, PGE-bearing UG2 Reef ore from the Dishaba Mine, South Africa, and fresh gabbronorite sourced from the Black Hill Norite Complex, South Australia. OREAS 84 has been characterised using the following methods:

  • Lithium borate fusion with X-ray fluorescence
  • Full ICP-OES and ICP-MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl) digestion
  • Sodium peroxide fusion or lithium borate fusion with full ICP-OES and ICP-MS suites
  • Sulphur by infrared combustion furnace

Certified values for applicable analytes are operationally defined for each method, with results under OREAS ISO 17034 scope of accreditation.
