  • 某低品位含金硫精矿生产工艺研究……汪勇,刘志斌,姜亚雄,段胜红,尹福兴
  • 摘 要:针对某含金硫精矿性质,开展了直接再磨氰化浸出金银—浸渣销售、焙烧制酸—烧渣再磨氰化浸出金银、焙烧制酸—氯化法提取有价金属等选冶工艺试验研究,并从产品方案、技术、经济、现场管控等方面对各种处置方式进行了对比分析。结果表明:相比其他几种工艺,含金硫精矿焙烧制酸—氯化法提取有价金属工艺可以明显提高有价金属回收率,获得金综合回收率81.67 %、银综合回收率54.81 %、铜综合回收率77.52 %、硫回收率90 %的较好指标。

    Study onthe production process of a low-grade gold-bearing sulfide concentrate……Wang Yong,Liu Zhibin,Jiang Yaxiong,Duan Shenghong,Yin Fuxing

    AbstractAccording to the property of a gold-bearing sulfide concentrate,the papercarried out experimental research on metallurgical processes,being flotationconcentrate regrinding prior to cyanidation leaching of gold andsilver-leaching tailings for sale,roasting and acid making-calcine regrindingprior to cyanidation leaching of gold and silver,roasting and acidmaking-valuable metal  extraction bychlorination,and compared and analyzed them in terms of product plan,technology,economyand field management.The results show that compared to other processes,thegold-bearing concentrate roasting and acid making-valuable metals extraction bychlorination process can significantly increase the recovery rate of valuablemetals,obtaining a gold comprehensive recovery rate of 81.67 %,silvercomprehensive recovery rate of 54.81 %,copper comprehensive recovery rate of77.52 % and sulfur comprehensive recovery rate of 90 %,which are fairly goodindex.
