摘要
介绍了电钴阴极表面长气孔的原因,并进行了针对性的分析和研究,同时提出了解决方案,提出了以P206萃取除Cu代替Na2S沉淀除Cu的改进措施。
The cause of causing gas hole on surface of electrical cobalt is discussed,analyzed and studied in detail. When Cu is removed by solvent extraction with P206 instead of precipitation with sodium sulphide, number of gas hole reduce and Co recovery increase about 2 to 3 percent.
