Technological Study on Germanium Recovery from Germanium-containing Polymetallic Materials AITranslate
Abstract AITranslate
Germanium-containing polymetallic materials were pretreated progressively with hydrochloric acid-ammonium fluoride-potassium,and then separated by distillation using hydrochloric acid to extract germanium tetrachloride.The final recovery of germanium is about 95.20%.The dosages were systematically studied through experiments of pretreatment hydrochloric acid,ammonium fluoride,potassium permanganate and distillation hydrochloric acid,and then optimum process conditions were determined.Compared with the conventional hydrometallurgical process of sulfuric acid leaching-tannin precipitation-germanium concentrate-hydrochloric acid distillation for germanium extraction,the recovery of germanium in the above process is improved by about 21%.
