本文对铜官山铜矿尾矿再选的采矿、选矿进行了一般的描述,並对生产中存在的一些问题进行了分析和讨论。铜官山铜矿老尾矿再选的生产实践表明:采用现行工艺流程、设备和操作条件对现有尾矿中有工业价值的资源进行再回收,在技术上是可行的,经济上是合理的。同时,仍需重视综合回收和不断提高选别指标,以使经济效果更明顯。更具现实意义的是:尾矿再选为综合利用国家资源,治理环境污染,利用选矿闲置设备提供了新途径。
This paper gives a general description of the mining and beneficiation of tailings re-election at Tongguanshan Copper Mine, and analyzes and discusses some problems in production. The practice of re-election of old tailings in Tongguanshan Copper Mine shows that it is technically feasible and economically reasonable to recycle the resources of existing tailings in the existing tailings with the current technological process, equipment and operating conditions of. At the same time, it still needs to pay attention to comprehensive recovery and continually raise seismological indicators in order to make economic effects more obvious. More realistic meaning is: tailings re-election for comprehensive utilization of national resources, environmental pollution control, the use of idle processing equipment provides a new way.
