The X-ray diffraction(XRD) results from the baked slag prove that Li and Al are transformed into Li2SO4 and Al2(SO4)3 just after decomposition by sulfuric acid. The only real noticed phase is SiO2 in the XRD patterns of leach residue, indicating that Li, Al and P are all transformed into soluble https://sergioufmta.creacionblog.com/19850052/lepidolite-and-lithium-no-further-a-mystery
