The X-ray diffraction(XRD) effects on the baked slag prove that Li and Al are transformed into Li2SO4 and Al2(SO4)3 just after decomposition by sulfuric acid. The one observed period is SiO2 from the XRD styles of leach residue, indicating that Li, Al and P are all transformed into soluble substances https://williamw356dqd3.tnpwiki.com/user
