Method for comprehensively recovering cerium and lanthanum from waste glass powder

The invention discloses a method for comprehensively recovering cerium and lanthanum from waste glass powder, and belongs to the technical field of resource recycling. The method for comprehensively recovering the cerium and the lanthanum from the waste glass powder comprises the following steps: uniformly mixing the waste glass powder and concentrated sulfuric acid, putting the mixture into a muffle furnace, carrying out primary roasting to obtain a roasted material, and then, carrying out water leaching on the roasted material to obtain a cerium and lanthanum-containing leachate and leaching residues; precipitating the cerium-lanthanum-containing leaching solution to obtain rare earth oxalate and a precipitated solution, and returning the precipitated solution to the previous water leaching procedure; wherein a precipitant adopted for precipitation is oxalic acid; and the rare earth oxalate is placed in the muffle furnace to be subjected to secondary roasting, and the cerium-lanthanum-rare earth mixture is
