Precious and base metals hydrometallurgy

Quantitative mineralogy characterisation and predictive modelling of hydrometallurgical performance

Page 2 of 9

The identification and analysis of the complex assemblages of minerals in ores requires a range of techniques and skills. Our expertise in this area includes:

  • quantitative x-ray diffraction analysis of concentrates, ores, leach residues and scale materials 
  • in situ x-ray diffraction capability to follow mineralogical changes in real time under simulated industrial conditions
  • synchrotron and neutron diffraction capability for studies into the mechanism and kinetics of crystallisation and crystal growth

  • automated scanning electron microscopy (SEM) analysis of ores and concentrates with mineral association and mineral liberation analysis (using QEMSCAN)
  • surface analysis using x-ray photoelectron spectroscopy (XPS)
  • TGA/TGA MS and vibrational spectroscopy (FTIR, FT Raman)
  • diagnostic and sequential leaching tools
  • x-ray microtomography (non-destructive analysis).

Our researchers are using the above tools to predict the process performance of ores based on their mineralogy and geology, an approach known as geometallurgy.
