The invention belongs to the field of metallurgy and particularly relates to a method for recycling vanadium from vanadium-containing corundum slags. A technical problem needing to be solved in the invention is to provide a method for recycling vanadium from ferrovanadium smelting vanadium-containing corundum slags. When corundum slags with a low vanadium content, produced in a ferrovanadium smelting process, are used as a fettling material to fettle a smelting electric furnace instead of part of magnesia, corundum slags with a high vanadium content, after being mixed with vanadium oxide, aluminum shots and iron grit in batches, are filled into the smelting electric furnace to carry out multi-phase arc smelting. When the vanadium contents in the slags in the first and second phases are separately reduced under 0.40% and 0.60%, slags are tapped. When the vanadium content in the slags in the third phase is reduced under 1.50%, slags and iron are simultaneously tapped, poured in an ingot mold and cooled. The method not only can recycle the vanadium in the vanadium-containing corundum slags and reduce the usage of fettling magnesia, but also can reduce the waste slag producing quantity of a smelting system.
