Resource comprehensive utilization method of germanium extraction residues

The invention belongs to the technical field of solid waste comprehensive utilization, and particularly relates to a resource comprehensive utilization method of germanium extraction residues. Germanium extraction distillation residues are used as raw materials, the distillation residues are treated through a sodium salt roasting method, then germanium-containing leachate is obtained through leaching, germanium-rich solution is obtained after silicon-aluminum precipitation impurities are removed through a coprecipitation method, and recycling of germanium is achieved. Adding a calcium-magnesium admixture, an active silicon-aluminum component and water into the leaching residue and the silicon-aluminum precipitate, stirring to form slurry, and directly forming and curing the slurry to form artificial stone or curing/stabilizing the arsenic-containing dangerous waste residue. According to the resource utilization method, waste residues are not generated in the implementation process, the germanium-rich solution
