| 摘 要： | 试验研究了二丁基卡必醇(DBC)从含金约20 mg/L的HCl-HAuCl4溶液中萃取金的方法。通过分析有机相组成、萃取时间、温度、相比对萃取金的影响,获得萃取金的基本规律,实际生产含金19 mg/L的料液,萃取回收率为97.01%。试验结果显示DBC能有效萃取低浓度金。

| Abstract: | We study the method of gold extraction from HCl-HAuCl4 solution with contenting 20 mg/L gold by DBC.Though investigating the effect of organic phase composition,extraction time,temperature and phase ratio on gold extraction,we obtain the basic regularity of gold extraction,the liquid with contenting 19 mg/L gold from practical production,and the recovery of extraction is 97.01%.The results indicate that DBC can extract gold effectively from low concentration of gold. |
