由硫酸锌废渣制备二氧化锗的研究

Preparation of germanium dioxide from waste residue of zinc sulfate

采用催化、酸浸、蒸馏等工艺，有效地回收了硫酸锌废渣中的锗，为锗的获取提供了一条经济、可行的途径。

Germanium in the waste residue of zinc sulfate can be effectively recovered through steps of catalysis,acid- leaching arid distillation.The process provides an economic and practical route for obtaining germanium.
