Processing technique for recovering germanium from zinc oxide dust are introduced, including the status quo of conventional leaching, high-pressure leaching, ultrasonic-enhanced leaching and leaching with microwave pretreatment, and their advantages and disadvantages are then analyzed based on comparison. Furthermore, techniques for extraction and concentration of germanium from the obtained leachate are also compared with each other, and the research directions in the future is proposed for recovering scattered element germanium from zinc oxide dust, which provides a reference for the progress in this field.
