采用焦炭还原挥发法处理湿法炼锌浸出渣,只要适当增加炉内氧化气氛,加大气流速度,就可提高浸出渣中铟、锗、镓的挥发率,而锌的挥发率仍可保持在90%以上。
The method of coke reduction and volatilization to treat leaching slag by wet-process zinc leaching can increase the volatilization rate of indium, germanium and gallium in the leached slag as long as the internal oxidation atmosphere and the air flow rate are appropriately increased, while the volatilization rate of zinc can be maintained at More than 90.
