Overview

Dr Elaine Wightman has worked extensively with automated image analysis techniques, such as MLA and QEMScan, to characterise material throughout the mineral processing chain, from exploration drill cores, comminution, flotation, tailings and smelter products. She is currently the manager of the Mineralogical Services group at the Julius Kruttschnitt Mineral Research Centre which supports research at the Centre through the provision of a number of mineral characterisation tools including: the Mineral Liberation Analyser (MLA), X-ray tomography, X-ray fluorescence (XRF) and optical microscopy. Elaine’s most significant contribution to the field of process mineralogy relates to her involvement in research programs which seek to understand the contribution from the physical characteristics of particles to their behaviour during processing. This work has resulted in a number of publications in international journals and conference proceedings as well as the recently released SMI-JKMRC monograph “Process Mineralogy”.
