Process Optimization of Germanium Enrichment from Fly Ash by Second Enrichment Process at High Temperature AITranslate
Abstract AITranslate
Using fly ash with germanium as the raw material,the enrichment of Ge from the fly ash was carried out by second enrichment process at high temperature.The effects of C content and sintering temperature on the volatilization rate of Ge were mainly studied,and the reasons were analyzed.The results show that appropriate C content and sintering temperature can promote the reduction and volatilization of Ge in fly ash.Excessive C will reduce part of iron oxides to Fe.And then Fe combines with Ge to form germanate,which is difficult to volatilize,affecting the enrichment and volatilization of Ge.Too high sintering temperature makes C not fully combusted to form CO,and part of Ge combines with CaO and MgO to form composite oxide,which reduces the volatilization rate of Ge.Under the optimum conditions of sintering temperature 1 700 ℃,C content 1%,basicity 1.0 and duration time 1 h,the Ge content of the pretreated fly ash is the lowest and the Ge volatilization rate reaches 96.2%.
