摘　　要：矿产资源的开采不可避免会混入围岩和夹石,造成出矿品位的降低,且随着矿产资源的大量开发利用,高品位和易选矿产资源储量日益减少,低品位和复杂难选矿产资源的经济高效开发利用愈发迫切。预选抛尾技术的应用,对提高入选矿石品位、减少磨选矿量、降低细粒尾矿排出量、提高资源利用率及减少环境污染等意义重大。从光电选矿抛尾、重选抛尾、磁选抛尾、浮选抛尾以及联合工艺抛尾,分别介绍了预选抛尾技术的现状和进展,并指出了各种预选抛尾技术的优势和不足,每种预选抛尾技术都有其特有的优势,联合工艺抛尾将是解决低品位矿产资源经济高效开发利用的重要技术突破,预选抛尾将成为选矿中一个通用必备的工艺环节。The mining of mineral resources will inevitably mix with surrounding rock and rock inclusion,resulting in the reduction of ore grade,with the development and utilization of a large number of mineral resources,the reserves of high-grade and easy to concentrate mineral resources are decreasing,and the economic and efficient development and utilization of low-grade and complex refractory mineral resources is becoming more and more urgent.The application of preconcentration for tailing discarding technology is of great significance to improve the grade of ore,reduce the amount of grinding,reduce the discharge of fine tailings,improve the utilization rate of resources and reduce environmental pollution.Be based on discarding of tailings by photoelectric beneficiation,gravity separation,magnetic separation,flotation,combined beneficiation process,the present situation and progress of preconcentration for tailing discarding technology are introduced respectively,and points out the advantages and disadvantages of all kinds of preconcentration for tailing discarding technology,each preconcentration for tailing discarding technology has its unique advantages,the combined beneficiation process be solve an effective development and utilization of low-grade mineral resources with an important technological breakthrough,preconcentration for tailing discarding technology will become a general and necessary process in mineral processing.
