摘要:
为了高效回收铅锌尾矿中的铅(Ⅱ），以柠檬酸钠为浸出剂，双氧水为氧化剂，研究了铅锌尾矿中重金属铅(Ⅱ）的选择性浸出过程，探讨了柠檬酸钠浓度、双氧水浓度、pH、固液比、浸出时间等因素对浸出率的影响机制。结果表明：当柠檬酸钠浓度为0.50 mol/L，双氧水浓度为0.02 mol/L，pH为7，固液比为1∶100 (g/mL)，浸出反应时间为360 min时，Pb2+的浸出率为90.1%，且Zn2+、Ca2+、Fe3+、Mg2+的浸出率分别为9.1%、57.6%、2.9%、1.7%，实现了Pb2+的高效浸出，同时抑制了Zn2+、Fe3+此类重金属的浸出率，为后续浸出液中Pb2+的选择性分离回收降低了难度。
Abstract:
To efficiently recover lead (Ⅱ) from lead-zinc tailings, a selective leaching process was investigated using sodium citrate as the leaching agent and hydrogen peroxide as the oxidant. The effects of sodium citrate concentration, hydrogen peroxide concentration, pH, solid-to-liquid ratio, and leaching time on the leaching rate were examined. Results showed that the leaching rate of Pb2+ reached 90.1%, at a sodium citrate concentration of 0.50 mol/L, hydrogen peroxide concentration of 0.02 mol/L, pH of 7, solid-to-liquid ratio of 1∶100 (g/mL), and leaching time of 360 min. Meanwhile, the leaching rates of Zn2+, Ca2+, Fe3+, and Mg2+ were 9.1%, 57.6%, 2.9%, 1.7%, respectively. This indicates that efficient leaching of Pb2+ was achieved while suppressing the leaching of competing heavy metal ions such as Zn2+ and Fe3+, thereby reducing the difficulty of subsequent selective separation and recovery of Pb2+ from the leachate.
