Abstract: A method for extracting lithium metal ions from glass includes contacting the glass with a molten salt bath for a duration of time, wherein the glass includes lithium and the contacting the glass with the molten salt bath for the duration of time extracts at least 40% of the lithium metal ions from the glass. The method further includes removing residual solids from the molten salt bath, wherein the residual solids include residual glass having a reduced concentration of lithium. The method further includes precipitating lithium metal ions from the molten salt bath to produce a solid precipitated lithium salt and separating the precipitated lithium salt from the molten salt bath.
