从钴渣中回收钴的研究进展
|
摘要
钴渣是湿法炼锌净化过程中产生的固体废弃物,常含有钴、锌等有价金属,具有很高的回收利用价值。本文综述了近年来国内外从湿法炼锌净化钴渣回收钴的方法,介绍了氧化沉淀法、选择性浸出法、β-萘酚沉钴法、氨-硫酸铵法、溶剂萃取法的原理,分析了各方法的优缺点和应用前景,认为溶剂萃取法有较好应用前景。
Cobalt residues are by-products in the purification process of zinc hydrometallurgy,which contains many valuable metals such as zinc,cobalt,and the residues have great recycling and utilization value.The methods for recovering cobalt from purification cobalt residues of zinc hydrometallurgy are summarized. The principle of oxidation precipitation method,selective leaching method,beta-naphathol precipitation method,ammonia-ammonium sulphate method,solvent extraction method is introduced,respectively. The advantages and disadvantages of these methods and application prospects are discussed.The solvent extraction method is regarded as better application prospect.
