本文在锌冶炼浸出过程中采用中和沉淀法处理某厂高锗锌焙砂，重点考察了浸出液Ｆｅ／Ｇｅ摩耳比，温度及时间对除锗的影响；随着Ｆｅ／Ｇｅ 摩尔比的增加，上清液中锗的浓度降低；随着温度的增加，上清液中锗的浓度急剧增大，时间对除锗影响不大。
In the process of zinc smelting leaching, a high-germanium zinc calcine was treated by neutralization and precipitation method. The influence of Fe / Ge molar ratio, temperature and time of leaching solution on the removal of germanium was investigated. With the increase of Fe / Ge molar ratio , The concentration of germanium in the supernatant decreased; with the increase of temperature, the concentration of germanium in the supernatant increased sharply, and the time had little effect on the removal of germanium.
