摘要:

        对贵州某地混合铜矿石进行了选矿试验研究。原矿入选品位Cu 1. 27% , Ag 3. 80 g/t,含As 4. 46 g/t,铜氧化率为23. 87%,属混合铜矿。根据矿石性质,分别拟定并开展了“氧硫混选”“氧硫分选”和“浮选尾矿酸浸”3种选铜工艺的探索对比试验,试验结果表明,“浮选尾矿酸浸”是适宜的选铜流程。试验表明:1)在较佳的分选条件下,原矿经“浮选尾矿酸浸”联合流程选别后,可获得铜精矿产率4.41%, Cu品位20. 52%、回收率73. 05 %; 浸液铜品位880.00 mg/L、浸出率14. 16%,铜总回收率87. 21%的技术经济指标。铜得到了回收利用。

Abstract:

     A beneficiation test of a sulfide-oxidized copper ore from Guizhou was studied.  Ore milling grade is Cu:1. 27%Ag:3. 80g/tAs 4. 46g/t and the oxidation rate of copper is 23. 87%. It belongs to the mixed copper. According to the ore propertiesa comparative test was performed on the three kinds of copper extraction processes, which are oxygen sulfur mixtureoxygen sulfur separation and flotation tailings acid leaching. The results show that copper concentrate grade of 20.52% and recovery of 73.05%; copper grade of 880.00 mg/L, leaching rate of 14.16% in medium and the total recovery of 87.21% was achieved through the whole closed trial, which was flotationtailings acid leaching.

Key words: sulfide-oxidized copper, flotation, leach
