| 摘 要： | 研究铅烟化炉氧化锌烟尘选择性氢化焙烧脱氟氯的过程。考察焙烧温度、焙烧时间、氯化钠和硫的加入量等因素对氟氯脱除效果的影响。实验结果表明，加入元素硫可以使氧化铅优先氯化并迅速挥发，避免物料烧结，有利于氟氯的脱除。在最佳条件下，焙烧产物中氟、氮的含量分别在0．015％和0．04％以下，满足湿法炼锌的要求。

| Abstract: | Selective chlorination roasting process for defluorination and dechlorination of zinc oxide dust from lead cleaning furnace is investigated The effects of process parameters on defluorination and dechlorination are studied Experimental results indicated that chlorination of PbO would not realize without element sulphur Under the optimum condition,contents of F and Cl in the roast product are below 0 015% and 0 04% respectively,which can meet needs for hydrometallurgical process of zinc |
