摘要
为从高硅含锗物料中提取锗 ,进行了直接蒸馏、加碱浸出、加碱焙烧和HF浸出试验 .结果表明 ,采用HF浸出、丹宁沉淀 ,然后烘干、焙烧、蒸馏的工艺提取锗 ,锗的回收率高达 92 %以上 .
Direct distillation, alkaline leaching, alkaline calcinations and HF leaching test were conducted to extract germanium from high silicon material containing germanium. Results show that the recovery of germanium can be over 92% by the technology of HF leaching, tannin precipitation, stoving, calcinating and distilling.
