| 摘 要： | 文章对褐煤共伴生元素锗采用在高温和弱还原气氛下易以低价锗氧化物和硫化物形式挥发出来,凝聚在带出物烟尘和飞灰表面上,通过收集烟尘等并对其处理可实现富集。相对于燃烧灰化法,采用低温灰化法效果更好,此方法能将有机物燃尽,简化了流程,避免了锗的损失。对于品位较低的含锗的烟尘用火法富集工艺进行富集,火法富集工艺相当于二次富集,它可使低品位含锗煤烟尘通过再次火法富集得到高品位含锗烟尘,从而实现了对褐煤共伴生稀有元素的提取,回收率为含量的90%。

| Abstract: | Being treated in a high temperature and weak reduction atmosphere,the lignite is easy to valotilize in the form of germanium oxide in low price and germanium sulfide which cohesion on the surface of smuts and ash.This research is about collecting and treat with the smuts so as to finish the enrichment.Low temperature ashing method was better relative to the combustion method,This method was able to burn organic matter,simplify the process and avoid the loss of germanium.For lower grade dust containing germa... |
