Effect of SiO on Ge Extraction from Germanium Dust by High Temperature Enrichment-Hydrochloric Acid Leaching Distillation AITranslate
Abstract AITranslate
In order to effectively recover Ge from germanium dust,the germanium dust was treated by se-condary enrichment at high temperature-hydrochloric acid leaching distillation.The interaction between SiO2 and GeO2 and the effect of SiO2 on extraction of Ge by hydrochloric acid leaching distillation were studied.Different proportions of SiO2 and GeO2 were treated at different temperatures for 6 h.The phases after treatment and their effects on hydrochloric acid leaching distillation were analyzed.The results show that with the increase of treatment temperature,the content of GeO2 in SiO2 continuously increases.When the treatment temperature is higher than 1 140 ℃,GeO2 can be completely dissolved in SiO2,and the recovery rate of Ge by hydrochloric acid leaching distillation is only about 11.3%.After adding CaO to SiO2-GeO2 system,GeO2 and CaO can form CaGeO3,which greatly reduces the amount of GeO2 dissolved in SiO2,and improves the recovery rate of Ge by hydrochloric acid leaching distillation.After adding CaO with the same molar ratio as GeO2 at 1 140 ℃,the recovery rate of Ge by hydrochloric acid leaching distillation increases from 11.25% to 87.24%.
