| Description: OREAS 317 has been prepared from a blend of barren black slate and various Zn-Pb-Ag ore and concentrate materials. This includes materials from the Dugald River, Black Star and Cannington deposits located in Northern Queensland, Australia. Twenty-six commercial analytical laboratories participated in the program to certify: - Majors & base metals by oxidising fusion with X-ray fluorescence finish;
- Loss on ignition at 1000° Celsius;
- Total Sulphur by infrared combustion furnace or C/S analyser;
- Full ICP-OES and MS elemental suites by peroxide fusion;
- Full ICP-OES and MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl) digestion;
- Full ICP-OES and MS elemental suites by aqua regia digestion.
