摘　　要：随着我国矿产资源的不断开发与利用,天然高品位矿石资源逐步减少,低品位矿石成为目前我国矿产资源的主要来源,因此,预选抛废成为一个必要的选矿环节。重点阐述了人工拣选抛废、光电选抛废、磁选抛废、重选抛废以及浮选抛废五种抛废技术,并介绍了不同技术在预选抛废时使用的设备和工作原理,指出了各种预选抛废技术的优缺点,为预选抛废技术能进一步工业应用提供了一定借鉴意义。With the continuous development and utilisation of mineral resources in China,the amount of natural high-grade ore resources has gradually decreased,making low-grade ore the main source of mineral resources in China.Consequently,preconcentration and discarding technology have become a necessary step in mineral processing.This paper focuses on five kinds of waste-disposing technologies:manual picking,photoelectric selection,magnetic separation,gravity beneficiation,and flotation.It introduces the equipment and working principle of different technologies used in preconcentration and discarding,highlighting their advantages and disadvantages.Overall,this study provides a reference for the further industrial application of preconcentration and waste disposal technology.
