| 摘 要： | 为简化含锗烟尘浸出过程，提出一段硫酸浸出工艺。浸出工艺条件为：浸出温度90℃，初始硫酸质量浓度120g／L，液固比8mL／g，浸出时间2．5h，搅拌转速120r／min。在该条件下，锌、锗浸出率分别为99．1％和87．61％左右，最终硫酸质量浓度约34．80g／L。去除不溶性锗后，锗浸出率可达到97．21％。

| Abstract: | To simplify the leaching process of germanium fly ash, the one stage sulfuric acid leaching process was studied. The result shows the leaching processing as following： leaching temperature 90℃ initial sulfuric acid concentration 120 g/L, ratio of hquid to solid 5 mL/g, leaching time 2 h, and mixing speed 120 r/min. Under these conditions, the leaching rates of Zn and Ge were about 99.1% and 87.61%, and the concentration of end acid is about 34.80 g/L, and by removal of insoluble germanium, the leaching rate of Germanium could be about 97.21%. Zinc and Germanium can be effectively leached from Germanium fly ash in the leaching process, and the leaching technique is effective and stable. |
