Bibliography: leaves 99-101. / Automatic ore sorting machines are in common use in the mining industry. These machines generally separate valuable mineral-bearing rocks from waste rocks. At the Premier Diamond Mine in South Africa kimberlite, a diamond-bearing rock is separated from gabbro which is a waste rock. Work had been conducted previously in the Department of Electrical Engineering at the University of Cape Town to find a viable method for discriminating between gabbro and kimberlite. A technique using microwave irradiation attenuation was successful when using parallel-sided smooth-surfaced rocks. This technique used linearly polarized square antennas at 35GHz. Problems were experienced, however, with irregu1arly shaped rock s. The aim of the present study was therefore to deve1op a technique which will sort irregularly shaped rocks and eliminate the problems associated with them.
