【摘要】：以电解法处理含镍浓缩液并回收镍,考察了电流强度、镍离子浓度、温度、pH和缓冲溶液对镍回收效果的影响。结果显示,以钌铱涂层钛板为阳极,在极距为20 mm、电流15 A、温度50℃、镍离子质量浓度为20 g/L并通气搅拌的条件下,镍回收率最高达到85.1%,相应的电流效率为51.8%。正交试验结果表明,镍回收率影响因素的大小顺序是电流镍离子浓度pH温度。
[Abstract]:Nickel concentrate was treated by electrolysis and nickel was recovered. The effects of current strength, nickel ion concentration, temperature, pH and buffer solution on nickel recovery were investigated. The results show that the highest recovery rate of nickel is 85.1 and the corresponding current efficiency is 51.8 under the conditions of 20 mm, current 15A, 50 鈩，
