光电拣选设备研究与应用进展

Research and application progress of photoelectric sorting equipment

随着矿产资源的高强度开采,矿石贫化加剧,对后续选矿作业带来了不利影响。光电拣选作为一种重要的预选技术,可提高矿石入选品位、减少环境污染、提高企业经济效益,具有广阔的应用前景。重点介绍了光电拣选设备组成及工作过程,简述了国内外光电拣选设备的研究进展,总结了色选机、X射线辐射拣选机、放射性拣选机、近红外射线拣选机、微波加热拣选机等在选矿领域的应用现状,并指出三维(3D)扫描技术、多类型传感器组合应用技术、智能拣选大数据技术等在光电拣选中的应用以及光电拣选设备的智能化、高效化和精准化等是未来的重点研发方向。

With the massive exploitation of mineral resources,the ore dilution is being intensified,which badly affected the subsequent mineral processing operations.As an important pre-concentration technology,photoelectric sorting facilitates the increase of the feed grade,lessens environmental pollution,and enhances the economic benefits of enterprises,and has wide promising applications.In this paper the systematic configuration and working process of photoelectric sorting equipment was introduced,the research progress of photoelectric sorting technologies at home and abroad was briefly described,the applications of color sorter,X-ray radiation sorter,adioactive sorter,near-infrared ray sorter,microwave heat sorter which has been used in the field of mineral processing in recent years were summarized,and it is noted that the development of photoelectric sorting technology in the future should mainly focuses on three aspects:three dimensional(3D)scanning technology,multi type sensors combined application technology,and intelligent sorting big data technology,and intelligent,efficient and precise application will be the key research interests of photoelectric sorting equipment.
