【摘要】：以電解法處理含鎳濃縮液并回收鎳,考察了電流強(qiáng)度、鎳離子濃度、溫度、pH和緩沖溶液對(duì)鎳回收效果的影響。結(jié)果顯示,以釕銥涂層鈦板為陽(yáng)極,在極距為20 mm、電流15 A、溫度50℃、鎳離子質(zhì)量濃度為20 g/L并通氣攪拌的條件下,鎳回收率最高達(dá)到85.1%,相應(yīng)的電流效率為51.8%。正交試驗(yàn)結(jié)果表明,鎳回收率影響因素的大小順序是電流鎳離子濃度pH溫度。
[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，
