摘要
在粗镉生产工艺中,确定采用分段置换的工艺方法,定量加入锌粉,第一步只置换90%的镉从而控制杂质铊的含量,投入应用后,效果良好,分段及定量置换工艺可行。
In raw cadmium production process,the step replacement and quantitatively adding zinc powders are used to control the impurity content.By using this technology, only 90% cadmium is replaced at the frist step to control the impurity thallium content.After putting the technology into application,the better result has gain,and the method is feasible.
