Method for recovering lithium from waste glass powder

The invention provides a method for recovering lithium from waste glass powder, and belongs to the technical field of solid waste reutilization, the method comprises the following steps: S1, crushing and screening the waste glass powder containing lithium element to obtain powder A; s2, uniformly mixing the powder A with a sodium-containing material to obtain a mixed material, and roasting the mixed material in a high-temperature furnace to obtain clinker B; s3, grinding the clinker B, then adding the clinker B into water or a low-acid solution, carrying out ultrasonic leaching, then filtering to obtain filtrate C and a filter cake, and washing and drying the filter cake to obtain filter residues D; and S4, freezing and centrifuging the solution C, removing a sodium-containing material, removing impurities and purifying the solution to obtain a high-purity high-lithium solution E, adding a sodium carbonate solution into the solution E, and filtering and washing to obtain a lithium carbonate product.
