Other metal components could not be removed by washing, therefore their proportions increased on account of removal of halogenide in filtered residue. As a result, washing could remove K, Na, Cl and Br from fly ash, which was also beneficial for ball-milling treatment [18]. For filtered liquid, metal elements were mainly K and Na.
