摘要
进行了焙烧脱氟氟-酸浸-氧化除杂-电解工艺处理铅烟化炉次氧化锌的研究。试验结果：锌直收率87．02％，回收率89．25％，阴极锌质量100％达0^#锌品级。
The research is made on the process for treating secondary zinc oxide from lead fuming furnace, which consists of removing fluorine and chlorine by roasting- acid leaching -removing impurities by oxidizing - electrowinning. The test results show that the direct zinc recovery is 87.02 %,the overall recovery rate is 89.25% and 100% of cathode zinc is in compliance with Grade 0^#.
