摘 要：用镍精矿－活性阳极泥－亚硫酸方法,研究了镍电解阳极液除铜效果;通过正交实验,查明了影响残铜量和mCu/mNi2个指标的主要因素和次要因素;得出最佳工艺条件是:镍精矿的质量浓度为0.30 g/L亚硫酸体积分数为15.0 ml/L阳极泥质量浓度为3.30 g/L阳极泥活度为30%,反应温度为85℃,起始pH值为3.5,反应时间为40min.
Abstract: The remove of copper from anode solution in nickel ectrolyte has been studied usingthe nickel concentrate-activited anode slime-sulfurous acid.The main factors to affect bothcopper content remaining in the solution and ratio of mCu/mNi the slag have been ascer-tained by means of orthogonal experinient.It is found that the best condition is as follows :nickel concentrate 0.30 g/L,sulfurous acid 15.0 mL/L,anode slirne 3.30 g/L, activity ofanode slime 30%,temperature of reaction 85℃ starting pH 3.5,time of reaction 40 min.
