Study on Occurrence State of Germanium in the Coal Ash AITranslate
Abstract AITranslate
The germanium content in the coal ash containing germanium was measured with titration meth- od,and other chemical components were tested by ICP. The phase composition of the coal ash containing germanium was studied by ore microscope,XRD and SEM-EDS. The results show that the content of SiO2 and iron oxide are the highest, followed by Al2O3 ,CaO and MgO, the carbon content greatly fluctuates, and arsenic content is also high. Before carbon removal,germanium dispersedly exists in various phases of the coal ash containing germanium. Germanium content is relatively higher in the phases with high SiO2 and iron oxide content, and lower in carbon particles. After carbon removal, germanium-rich phase appears in coal ash containing germanium, mainly existing in the form of Mg3 Fe3 GeO3 complex oxide and inlaid in oxides such as SiO2 and CaO.
