【摘要】：用草酸銅沉淀法回收含銅硝酸退鍍液中的銅并再生硝酸。研究了草酸加入系數(shù)(n_(草酸)∶n_(銅))、反應(yīng)時間及反應(yīng)溫度等對沉淀效果的影響。確定的最佳工藝條件為:Cu~(2+) 136.52g/L,草酸加入系數(shù)0.9,攪拌速率300r/min,28℃,60min。在此工藝條件下,銅的沉淀率約為90%,草酸殘留率小于1%,草酸銅產(chǎn)品的純度達(dá)到98.33%。
[Abstract]:Copper was recovered and regenerated by copper oxalate precipitation method. The influence of the addition coefficient of oxalic acid (n _ (oxalic acid): n _ (Cu),) on the precipitation effect was studied. The optimum technological conditions were determined as follows: 1: Cu2 136.52 g / L, oxalic acid addition coefficient 0.9, stirring rate 300 r / min ~ 28 鈩，
