摘　　要：以硫酸锌-硫酸溶液模拟兰坪氧化锌矿反萃液,考察氨氮及有机杂质如260溶剂油和β-二酮对锌电积过程电流效率和电锌质量的影响。实验结果表明:氨氮对锌电积过程中电流效率和电锌质量基本无影响,而有机杂质260溶剂油和β-二酮影响较大。Stripping solution of Lanping zinc oxide ore was simulated with zinc sulfate and sulphuric acid.The effect of ammonium nitrogen and organic impurities such as 260 solvent oil,β-dione on the current efficiency and quality of electrolytic zinc in different concentrations was investigated.Experimental results show that ammonium nitrogen has no effect on zinc current efficiency or quality of electrolytic zinc,while effect of organic impurities such as 260 solvent oil and β-dione on zinc electrowinning process is larger.
