X-ray computed tomography (XCT) is a non-destructive technique originally developed for medical application. Over the past decade, XCT has been used to explore in 3D the distribution of pores and mineral phases in natural and synthetic samples across a range of scales (from 100s of metres down to <1 micrometre), leaving the samples intact for further characterisation using geochemical, optical and scanning-electron microscopy based techniques. The range of X-ray energies used allows the X-ray to be transmitted through dense and complex materials such as ore materials. The presentation will highlight some recent advances in 3D characterisation of ore materials (hosting Ni, Cu, platinum-group elements, Fe, graphite and gold) using X-ray computed tomography combined with 3D image analysis and quantification and micro-chemical and micro-textural techniques across a range of scales with implications from mineral exploration through to metal recovery and processing performance optimisation.
