WANG WENQIAN and GEORGE W. POLING, Department of Mining and Mineral Process Engineering, The University of British Columbia, Vancouver, B.C.

Devices and flowsheets for recovering fine placer gold are reviewed. Inefficiencies of gravity processing techniques are documented and discussed. Prospects of combining gravity and froth flotation techniques are presented. Possibilities of using other separation techniques, such as magnetic and electrostatic devices are also discussed.
