Synchrotron XFM and XANES Mapping of Visible and Invisible Gold in Polymetallic Legacy Tailings for Resource Valorisation (2026)
Abstract
This project uses advanced X-ray techniques at the Australian Synchrotron to map how gold occurs in historic mine waste from Queensland. The aim is to identify both visible gold and ¿invisible¿ gold locked within minerals, which is difficult to detect using conventional methods. By understanding where and how gold is hosted, the study will help design more efficient and environmentally responsible recovery strategies. Expected outcomes include improved resource recovery from existing waste, reduced environmental risks such as acid mine drainage, and new opportunities to extract valuable metals and sulphuric acid for use in the mining industry and agriculture.
