金的液-固浮选分离和富集研究

Study on liquid-solid floatation separation and enrichment of gold

研究了氯化十六烷基吡啶-KI体系分离金的行为及其与一些金属离子分离的条件。实验结果表明,在一定条件下,Au3+可与Cr3+、Mg2+、Zn2+、Fe2+、Mn2+、Al3+、Ni2+、Co2+、V(Ⅴ)和U(Ⅵ)定量分离。该方法简便迅速,不污染环境,在微量金的分离和富集分析中有一定的实用价值。

The behavior for flotation separation of Au3＋ with cetylpyridine chloride-KI system and the separation condition of Au3＋ with other metal ions were studied.The result showed that Au3＋ could be separated quantiatively from Cr3＋,Mg2＋,Zn2＋,Fe2＋,Mn2＋,Al3＋,Ni2＋,Co2＋,V（Ⅴ） and U（Ⅵ） by floatation in the given conditions.The method is simple,fast and environment-friendly.It is of practical value in the trace gold separation,enrichment and determination.The method is easy,rapid and no pollution to the environment,which shows certain practical value in separation and enrichment analysis of trace Gold.
