Precious and base metals hydrometallurgy
Quantitative mineralogy characterisation and predictive modelling of hydrometallurgical performance
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.
