一、前言我厂生产电解铜时产出的含镍溶液(成分见表1),不仅含酸高,含其他杂质也较高。过去直接用于镍系统生产电解镍,不但增大了电解镍生产中净化作业的负担和酸碱消耗量,而且两个生产系统之间难于平衡,常因此打乱正常的生产秩序。为解决这一问题,和增加我厂镍产品,决定生产硫酸镍。 I. Introduction I plant the production of electrolytic copper nickel solution (composition shown in Table 1), not only with high acid, containing other impurities are also higher. The direct use of nickel in the past to produce electrolytic nickel not only increased the burden of purification operations and the consumption of acid and alkali in the production of electrolytic nickel, but also made it difficult to balance the two production systems, thereby disrupting the normal production order. To solve this problem, and increase our factory nickel products, decided to produce nickel sulfate.
