Abstract

Abstract: As an advanced technology, Positron Emission Particle Tracking (PEPT) technology has been used in mineral processing industry. Mechanism and application of PEPT in mineral processing were outlined in present work. Application prospect of PEPT technology in mineral processing was also discussed. Results show that PEPT has proved to be an advanced technology in tracing particle trajectories in spiral concentrator, forth floation, hydrocyclone and milling processes, which has a remarkable influence in understanding mechanism and optimizing equipment. Future work should be done in tracing particle moving behavior in TBS, table concentrator, conditioning, etc, which would be a better understanding of these processes.
