摘　　要：针对某铜金矿石的性质,对该厂碎磨流程的常规碎磨工艺和半自磨工艺进行了比较。对比结果发现,两种工艺的Morrell粉碎比能耗估算和经营费用现值都非常接近,基于半自磨工艺的低经营成本,结合选厂的生产实践,最终推荐采用半自磨工艺。According to the characteristic of the copper gold ore,the detailed comparison crushing and grinding process design schemes is carried out for the ore concentrator,which includes the semi-autogenous grinding process and the conventional grinding process.Comparison results show kinds of scheme of Morrell crushing specific energy consumption and the expense present values are approximate in the two schemes;however,based on the various advantages of semi-autogenous grinding process and combining with production practice of the existing gold ore processing plant,the semi-autogenous grinding process is finally adopted in this ore processing plant.

关 键 词：碎磨工艺 粉碎比能耗 半自磨工艺 常规碎磨工艺 方案比较
