lixivium

The modified meerschaum was first used to recover gallium from acid lixivium of zinc residues and the experimental results were satisfactory.

采用改性海泡石从锌渣酸液中提取、回收稀散金属镓,取得了良好的试验结果。

The amount of electro-conductivityly: obtainingwater lixivium electroconductibility sirolan with their electroconductivity, and mid-rice blank reference should be the absolute value of< = 0 2.

电导率变化量：取水液用电导率仪测定其电导率，与空白对照液的差值的绝对值应≤02。
