Abstract: A process for recovering lithium from lithium-containing glass based materials includes providing lithium-containing particles comprising the lithium-containing glass-based materials; contacting the lithium-containing particles with calcium salts in water, wherein the contacting causes leaching of at least a portion of lithium ions from the lithium-containing particles into a first leachate of the first mixture; separating the first mixture into the first leachate and a first residue; and recovering lithium from the first leachate.

Abstract: Methods of recovering lithium from glass include crushing the glass to produce glass particles and contacting the glass particles with an aqueous leaching solution at a leaching temperature greater than ambient temperature and less than the boiling temperature of the aqueous leaching solution to produce a leachate slurry. The glass particles include lithium. The aqueous leaching solution includes sulfuric acid in water or sodium hydroxide in water. Contacting the glass particles with the aqueous leaching solution leaches greater than or equal to about 50% of the lithium out of the glass particles. The methods further comprise separating the leachate slurry to produce a solid residue and a leachate, the leachate comprising the lithium leached from the glass particles. The method further include recovering the lithium from the leachate through precipitation.

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.
