摘要
本文采用分步还原、梯级稀释理论从废镉渣中回收出了纯度高达99.5％的纯镉粉。从而为火法炼锌的厂矿,在回收镉方面研究出了能获得高附加值经济利润的简单回收工艺。
Based on the principles of fractional reduction and step dilution, when retrieving Cadmium from Cd dross, percentage purity of Cd powder can reach to 99.5%. For Zinc refiners adopting pyro-refining method, the method illustrated in this paper is a simple retrieving technique with additional high profits.
