摘要
Jungar mining is the most important coal base in China,which is associated with abundant Sc element in coal beds.The Sc element is concentrated in fly ash of the coal principal combustion product and full of value for extracting.The content of Sc in coal seam of Heidaigou opencast coal mine and distribution of Sc element in the process of extracting alumina from circulating fluidized bed fly ash by"one-step acid dissolution"are discussed to lay the foundation for concentration and extraction of Sc.The research results show that the average content of Sc is 0.0026%in the coal burning of Heidaigou opencast coal mine.
