Recovery Methods of Germanium

Article Preview

Abstract:

The paper overviewed the recovery methods of germanium, summarized the feature of those methods such as leaching with sulphuric acid, chlorination leaching- distillation, alkali decomposion, leaching with hydrofluoric acid, extracting, reduction and leaching germanium with microorganism. And introduced the principles ,technologies and disadvantages of those methods. Finally, prospected that microwave pretreatment technology and microwave directly leaching can be used in traditional methods such as acid leaching and alkali decomposion to improve the recovery rate of germanium by change insoluable germanium into soluble germanium and upgrade the leaching rate of germanium.
