摘要
将含锗石英玻璃废料在料碱质量比1∶4及820℃的条件下焙烧2.5 h,再经特殊工艺处理,然后进行酸化及蒸馏,锗的回收率由90%提高到93%以上.
By alkaline roasting 2.5 h at 820℃ and specially treatment ,acidify with sulphate acid and distillation et al. germanium is extracted from a quartz residue containing germanium. Results show that the recovery of Germanium can be rised from 90% to 93%.
