The present invention provides a germanium-containing copper dust comprehensive recovery process. While common valuable elements in copper dust are recovered, recovery of germanium is added. Techniques are adopted comprehensively. For example, a jarosite process is used for separation of iron and a tanning process is used for sediment. The most appropriate treating methods are adopted according to properties and characteristics of materials, and thus the recovery rate of germanium is higher than 70%. The advantages of the recovery process are that the acid leaching effect is the best; loss of the germanium is the smallest; impacts of iron on germanium extracting are removed; the extracting efficiency of germanium is raised, and thus economic benefit is enhanced.
