摘要/Abstract

摘要： 作为检测颗粒运动行为的先进手段，正电子发射型颗粒追踪技术(PEPT)近几年已在矿物加工领域有了一定的应用。本文主要就PEPT工作原理进行了简介，总结了该技术近几年在螺旋选矿、浮选、旋流器以及磨矿等工艺中的应用，就PEPT技术在矿物加工中的应用前景进行了分析。结果表明：作为一种先进的颗粒追踪技术，利用PEPT可以直观监测到颗粒在螺旋选矿机、水力旋流器以及浮选过程中的运动规律，也能对磨机运行状态以及研磨介质运动状态进行监测，这对明确设备运行机制具有重要意义。未来PEPT技术也应在TBS分选机、摇床、调浆机等设备中用于测定和表征颗粒运动状态，利用PEPT计算研究物料特性和结构参数对颗粒运动的影响，将有利于完善矿物加工理论，为设备的优化提供指导。

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.
