As an important secondary raw material, V‐bearing converter slag is of great interest for vanadium recovery. An economic, clean, and novel technique to recover valuable elements, such as vanadium, from waste slag involves three steps: (1) The selective concentration of the desirable element in a specific mineral phase (2) The selective coarsening of the mineral phase by precipitation and growth to a critical grain size in molten slag; (3) The selective separation of the enlarged mineral phase from the tailings by ore dressing or hydrometallurgical processes. Vanadium in the modified converter slag was concentrated into a specifically designed mineral phase called the V‐concentrated phase. This phase can be separated from the other slag phases by ore dressing.
