  • Extracting gold from gravity concentrates using grinding ...

    This thesis presents a novel chemical-free method of extracting Yukon placer gold from various secondary and tertiary gravity middlings. This method exploits the differences in relative malleability rather than density. At a certain point in gravity gold processing the middling material contains too many high density minerals to be amenable to further gold extraction through gravity ...
