Abstract AITranslate

Germanium was recovered from fly ash by ammonium fluoride-sulfuric acid leaching. In the process ,ammonium fluoride reacts with sulfuric acid to generate hydrogen fluoride as the destruction rea- gent of silica and calcium oxide in fly ash,sulfuric acid serves as the destruction reagent of magnesia,and sodium chlorate serves as the oxidant to oxidize Ge( Ⅱ ) into Ge(Ig),which can he dissolved into the leac- hing solution by sulfuric acid. Finally, germanium is precipitated with tannic acid. The above process has the advantages of high germanium recovery,low cost, low pollution and so on. Under the optimal technical conditions,the germanium recovery reaches 80.12% and the grade of resultant germanium concentrate is up to 4. 69%.
