Gold cyanidation barren solution is rich in copper/zinc cyano-complexes and possesses high recovery value. However, existing processes typically require the conversion of copper cyano-complexes into compound precipitates prior to smelting recovery, resulting in a relatively complex flowsheet and high energy consumption. To address this issue, a coupled process integrating ferrous precipitation and zero-valent aluminum reduction is proposed to achieve barren solution purification and valuable resource recovery. In this process, zinc cyano-complexes are first selectively precipitated by ferrous ions for zinc recovery; then, copper cyano-complexes are reduced by zero-valent aluminum assisted by ferrous ions to recover elemental copper; finally, ferrocyanide is precipitated by ferrous mass ions to recover Prussian blue. The results indicate that after treatment by this method, the total zinc concentration in the solution decreases from 1.95 g/L to 0.01 g/L, total copper mass concentration from 2.25 g/L to 0.03 g/L, and total cyanide mass concentration from 10.30 g/L to 0.20 g/L. The obtained zinc sludge contains over 22% zinc, the copper powder contains over 90% elemental copper, and the iron sludge contains over 50% Prussian blue. Economic analysis shows that the comprehensive reagent cost is approximately 78.4 CNY/m3 of barren solution, while the direct revenue from the produced elemental copper sludge is about 200 CNY/m3. This method provides a technical reference for the resource recycling and utilization of cyanide gold leaching barren solution.

金氰化贫液中富含铜/锌氰配合物,具有较高回收价值,但现有工艺通常须将铜氰配合物转化为化合物沉淀后再进行冶炼回收,流程较为复杂且能耗较大。针对该问题,提出采用耦合亚铁沉淀与零价铝还原联合工艺实现贫液净化与有价资源回收,先通过亚铁选择性沉淀锌氰配合物回收锌,再用亚铁辅助零价铝还原铜氰配合物回收单质铜,最后采用亚铁沉淀亚铁氰根回收普鲁士蓝。研究结果表明:采用该方法处理后,溶液中总锌质量浓度由1.95 g/L降至0.01 g/L,总铜质量浓度由2.25 g/L降至0.03 g/L,总氰质量浓度由10.30 g/L降至0.20 g/L;所得锌泥中含锌22%,铜粉含单质铜90%以上,铁泥含普鲁士蓝50%以上。经济性分析显示,综合试剂成本约78.4元/m3贫液,而产出单质铜泥的直接收益约200元/m3。该方法可为氰化浸金贫液的资源化回收利用提供技术参考。

金氰化贫液中富含铜/锌氰配合物,具有较高回收价值,但现有工艺通常须将铜氰配合物转化为化合物沉淀后再进行冶炼回收,流程较为复杂且能耗较大。针对该问题,提出采用耦合亚铁沉淀与零价铝还原联合工艺实现贫液净化与有价资源回收,先通过亚铁选择性沉淀锌氰配合物回收锌,再用亚铁辅助零价铝还原铜氰配合物回收单质铜,最后采用亚铁沉淀亚铁氰根回收普鲁士蓝。研究结果表明:采用该方法处理后,溶液中总锌质量浓度由1.95 g/L降至0.01 g/L,总铜质量浓度由2.25 g/L降至0.03 g/L,总氰质量浓度由10.30 g/L降至0.20 g/L;所得锌泥中含锌22%,铜粉含单质铜90%以上,铁泥含普鲁士蓝50%以上。经济性分析显示,综合试剂成本约78.4元/m3贫液,而产出单质铜泥的直接收益约200元/m3。该方法可为氰化浸金贫液的资源化回收利用提供技术参考。

Gold cyanidation barren solution is rich in copper/zinc cyano-complexes and possesses high recovery value. However, existing processes typically require the conversion of copper cyano-complexes into compound precipitates prior to smelting recovery, resulting in a relatively complex flowsheet and high energy consumption. To address this issue, a coupled process integrating ferrous precipitation and zero-valent aluminum reduction is proposed to achieve barren solution purification and valuable resource recovery. In this process, zinc cyano-complexes are first selectively precipitated by ferrous ions for zinc recovery; then, copper cyano-complexes are reduced by zero-valent aluminum assisted by ferrous ions to recover elemental copper; finally, ferrocyanide is precipitated by ferrous mass ions to recover Prussian blue. The results indicate that after treatment by this method, the total zinc concentration in the solution decreases from 1.95 g/L to 0.01 g/L, total copper mass concentration from 2.25 g/L to 0.03 g/L, and total cyanide mass concentration from 10.30 g/L to 0.20 g/L. The obtained zinc sludge contains over 22% zinc, the copper powder contains over 90% elemental copper, and the iron sludge contains over 50% Prussian blue. Economic analysis shows that the comprehensive reagent cost is approximately 78.4 CNY/m3 of barren solution, while the direct revenue from the produced elemental copper sludge is about 200 CNY/m3. This method provides a technical reference for the resource recycling and utilization of cyanide gold leaching barren solution.
