硫酸钴溶液深度净化的生产实践

Operational Performance of Deep Purification of Cobalt Sulphate Solution

研究拟定了净化工艺流程：粗氢氧化钴热水搅洗──氢氧化钴的还原溶解──次氯酸钠除锰──硫化钠沉铜──磷酸除锌。按拟定流程组织了小规模生产，可制出能由之产出T—2级氧化钴的硫酸钴净化溶液。

Deep Purifcation processes were developed,involving rough cobalt hydroxide stirring and washing with hot water, cobalt hydroxide reduction and dissolution;demanganese by using sodium hydrochlorite;precipitation copper by adding sodium sulphide;and dezinc wiht phosphorus acid the processes have been put into small-scale operation.Purified cobalt sulphate soultion has been yielded,and from it Grade T-2 cobalt oxid has been made,
