摘要
根据凡口铅锌矿锌精矿富含镓、锗的特点,采用加压浸出处理该锌精矿。重点考察了酸锌摩尔比、时间、添加剂、磨矿粒度、氧分压等因素对锌、铁、镓、锗浸出率的影响,在适宜工艺条件下,锌、铁、镓、锗的浸出率可分别达到98%、85%、85%、88%。
According to the characteristic of gallium and germanium rich in the zinc concentrate termine their influence on the extractions of Zn, Fe, Ga, Ge. The extraction rate of Zn, Fe, Ga and Ge could reach 98%, 85%, 85%, and 88% respectively under the optimum conditions.
