小型采砂船在老柞山金矿老尾矿回采生产中的应用

Application of small-sized dredge to the stoping of old tailing of Laozuoshan Gold Mine

综述了老柞山金矿尾矿库尾矿堆存及回收有价矿物试验情况 ;根据浮选工艺特点及技术要求 ,供矿量、供矿连续性及供矿浓度的稳定是保证生产正常进行的必要条件 ,选择了小型采砂船与大型搅拌槽相配置的联合回采工艺 ,并对回采工艺特点及应用效果作了扼要介绍。

The status of the old tailing stored in the tailing pool of Laozuoshan Gold Mine and the experiments of recovering valued mineral from the tailing were introduced.According to the experiments,it decided to recover gold copper mineral in the tailing by flotation technology.Due to this technology required quantitative ore feed with stable density and nice continuity,the small sized dredge together with large sized agitation tank were employed to stope the tailing achieving excellent effect.
