Efficient and clean germanium extraction method, system and process

The invention belongs to the technical field of chemical metallurgy, and particularly relates to an efficient and clean germanium extraction method, system and process, mixed acid of hydrochloric acid and sulfuric acid reacts with germanium-containing raw materials to rectify and extract germanium, so that chloride ions and distillation residues in hydrochloric acid are recycled. Distilled germanium tetrachloride steam is subjected to subsequent processing and purification; and directly reusing the distillation residual liquid for a smelting system, or reusing the sulfuric acid mother liquid for distilling and extracting germanium after filtering and separating. According to the method, germanium in the germanium concentrate is evaporated out in the form of GeCl4, only arsenic in germanium-containing raw materials and a small amount of metal consume chloride ions in hydrochloric acid, and the utilization rate of hydrochloric acid can reach 90% or above. 本发明属于本发明属于化学冶金技术领域，尤其涉及一种高效清洁的提锗方法、系统及工艺，使用盐酸与硫酸的混酸与含锗原料
