Title:
A METHOD AND SYSTEM FOR RECOVERING DIAMONDS FROM DIAMOND BEARING MATERIAL
Document Type and Number:
WIPO Patent Application WO2002047803
Kind Code:
A3
Abstract:
A method and system for recovering diamonds (45) from diamond bearing material sich as kimberlite ore or sea shells, comprises the steps of subjecting the material to a contactless disintegration stage (26). By convecting electrical energy into a pressure pulse (33) in an energy converter (34.1), the propagating pressure pulse (33) causes the material to disintegrate into particles (47) smaller than the diamonds. The particles and diamonds are then separated by known techniques.
