摘要
The present invention relates to a germanium and selenium-enriched glass fertilizer which fly-ash acts as main component and the method for producing the same. The process comprises adding coals and vitrified additives into boiler and burning to obtain flue gases which include germanium and selenium-enriched hyaline fly-ash, then cooling and seperating in the duster to obtain a germanium and selenium-enriched hyaline material, the processing to a germanium and selenium-enriched glass fertilizer. After being denitrified, desulphurized and defluorinated, the flue gases are discharged into air. The method is simple, and the products can be used as functional glass fertilizer which can prevent and treat cancer, and on the other hand as the industrial material for producing selenium and germanium. The process is one of the complex utilization methods of coal slags.
