OREAS 412

OREAS 412 is a magnetite-rich ore sourced from the Hawks Nest magnetite project located in South Australia, within the Woomera Prohibited Area (approx. 50 km southwest of Peculiar Knob). The certification program will include:

  • Iron Ore package by borate fusion with XRF
  • Multi-temperature LOI at 371° C, 425° C, 650° C and 1000° C
  • Full elemental suites by 4-acid digestion with ICP-OES/MS
  • SG by gas or liquid pycnometry
  • FeO by HF/H2SO4 digestion with titration
  • Magnetic Susceptibility by Satmagan 135
  • Davis Tube Recovery using 20-30g sample size with preferred settings: Stroke frequency 60/minute or 90/minute, Stroke length 38mm, Magnetic field strength 3000 gauss, Tube angle 45 degrees, Tube diameter 38mm, Washing time 20 minutes or until clear.
Note: Analyte values are indicative only and may change when certified.
