摘　　要：本文通过对铜渣选矿的典型性分析,归纳出取得良好技术经济指标的通用措施,采取渣包高温缓冷、渣堆场预破碎、半自磨工艺、阶段磨矿阶段选别、取消中矿单独再磨再选、组合用药、磁选回收铁和改善过滤性能等措施。提出了适合铜渣选矿的典型工艺流程,“粗碎+半自磨+粗磨+快速浮选+再磨+一粗三扫二精浮选+尾矿磁选”流程技术经济指标良好,可在类似项目上推广使用。Based on the typicality analysis of copper smelting slag beneficiation,this paper summarized the general measures to obtain good technical and economic indicators,such as high temperature slow cooling of slag ladle,pre-crushing,semi autogenous grinding process,stage-grinding and stage-separation,cancellation of separate regrinding of middling,combination of reagent,iron recovery by magnetic separation and improvement of filtration performance.this paper puts forward the typical process applicable for slag beneficiation as follows“Primary ore crushing+Semi-autogenous grinding+Coarse grinding+Speed flotation+Regrinding+Multiple flotation+Tailings magnetic separation”,this process has good technical and economic indexes and can be popularized in similar projects.
