The invention discloses a method for recovering carbonized silica powder, which belongs to the technical field of silicon carbide production. The method solves the problems of large pollution, little production power, low product content and high refinement content in the prior art can be solved. The method comprises the following steps: calcining a recovered material, mixing the calcined raw material and water as well as mixing slurry, introducing the material into a cyclone for rotational flowing; fully stirring the slurry after rotational flowing, beating the material into an acid bubble barrel, adding sulfuric acid for immersion and using a vacuum filtration filter for depickling; fully stirring the depickled slurry, adding sodium hydroxide for alkali washing and impurity removal, then using the vacuum filtration filter for dealkalization to obtain the dealkalized slurry; using a pump for beating the slurry after alkali washing into a moisture feeding barrel, stirring fully the material and beating the material to a taper grading overflow barrel for waterpower grading to obtain a product; respectively dehydrating and drying the product according to the models; placing the dried product into a feed mixer for batch mixing, uniformly granulating the material, and respectively sieving the product. The method can be used for recovering the carbonized silica powder.
