Deportment of gold in discharge samples from AC-POX/CIL circuits

Deliverables:

  • Evaluation of refractory gold in residual (unoxidized) sulphides using quantitative D-SIMS analysis:
    • Quantification of sub-microscopic gold content in sulphides of different morphological types
    • Quantification of the arsenic content
    • Mapping of the gold and arsenic distribution (optional)
  • Evaluation of gold trapped in primary FeOx and oxidation products by D-SIMS:
    • Quantification of sub-microscopic gold content in the iron oxides
    • Quantification of the arsenic content
    • Mapping of the gold and arsenic distribution (optional)
  • ToF-SIMS analysis of exposed gold with impermeable coatings: Hg, Ag, Cu, phosphates, arsenides, carbonates, et cetera.
  • Written report

Cost:
$3360 for 55 SIMS analyses
$3360 for 10 map plates (optional)
$2000 for ToF-SIMS surface analysis of 20 gold grains
