The new technology of tailings dewatering dry-discharge and directly piles , landfills or transports outside the dried tailings .Upon application of this technology , the ore dressing enterprises will no longer need to build large concentra-tor, tailings dam, long distance pipeline transportation of tailings and tailings dam backwater , thus save valuable construc-tion site and infrastructure costs , and avoid environmental problems and safety concerns during the operation , and enhance the utilization of return water from only 70%~75%to more than 95%, with zero drainage , and bring huge economic and social benefits.Through summery to the application , a set of methods of dry tailings discharge treatment for tailings disposal work are discussed for references .%尾矿脱水干排新技术，就是将尾矿进行脱水，干尾矿可直接干堆、填埋或外运的新技术。运用此项技术后，选矿企业将不再建设大型浓密机、尾矿坝、尾矿长距离输送管线及尾矿坝回水长距离输送管线，为企业节约宝贵的建设场地及大量基建费用；避免了尾矿库运行期间破坏生态环境和安全隐患大等问题；将回水利用率由原来只有70％～75％左右提高到95％以上，且实现生产零排水，经济和社会效益巨大。本文通过对尾矿脱水筛在尾矿干排系统中的技术应用的总结，概括出尾矿干排处理的一套方法，以期和大家共同探讨学习，做好尾矿处理工作。
