某铜冶炼炉渣回收铜的选矿工艺试验
|
摘要
某铜冶炼炉渣铜品位为0.98%,嵌布粒度细,易碎难磨,根据试验结果,在磨矿细度为90%(-0.074mm)时,以CaO为调整剂,KM-109为捕收剂,730A为起泡剂,经一粗二精一扫闭路流程分选,可获得品位13.18%、回收率79.77%的Cu粗精矿,且杂质含量符合产品质量要求,并对Cu粗精矿再磨后(80%,-0.037mm)一段精选即可获得品位21.06%、回收率61.02%的Cu精矿。
The copper grade in a copper smelting slag is 0.98%,the embedded granularity is relatively fine,and it is fragile and difficult to grind.According to the research results,when the grinding fineness of-0.074 mm was 90%,and CaO was selected as the regulator,KM-109 as collector,and 730 Aas foaming agent,a closed circuit flotation flowsheet of one-stage roughing,two-stage cleaning and one-stage scavenging was carried out.Finally,a copper concentrate with grade of 13.18%and recovery rate of 79.77% was obtained,and the impurity content of copper concentrate all met the requirements of product quality.After re-grinding the copper crude concentrate with grinding fineness of-0.037 mm occupying 80%,the copper concentrate with grade of 21.06% and recovery rate of 61.02%could be obtained through the one-stage cleaning.
