镇沅金矿破碎流程改造实践

Transformation practice of crushing circuit of Zhenyuan Gold Mine

对于含泥、含水较多的矿石,用传统的三段一闭路破碎流程容易造成矿石运转不畅,尤其是在只有雨季和旱季之分的云南哀牢山地区,旱季粉尘飞扬,雨季矿石流动不畅,严重影响矿山生产。将破碎加球磨流程改造为半自磨加球磨工艺后,车间环境得到显著改善,选厂处理能力大幅提高,企业生产效率和经济效益大幅提高,该矿的改造经验值得借鉴。

For the ore with high content of mud and water, traditional three stages crushing with one closed circuit caused ore transfer difficult ,especially in Ailaoshan area,Yunnan Province ,where just has rainy and dry season. The dust is rising in dry season and the ore flow is unsmooth in rain season, and these influence mine production seriously. After transformed the crushing and ball milling to semi-autogenous grinding and ball milling, the environment of workshop improved greatly,the throughput of concentrator increased,and the production and economic benefits also improved a lot. The transformation practice is worth use for reference.
