摘要： A method for purifying aluminum to provided which comprises the steps of maintaining aluminum as a starting material in a molten condition in N+1 vessels; wherein N+1 vessels for molten aluminum and N cooling bodies are provided which are immersed in molten aluminum in the vessels and upon which highly purified aluminum is crystallized on the surfaces thereof. The N+1 vessels are arranged sequentially from 1-st to (N+1)-th and the N cooling bodies are sequentially arranged from 1-st to N-th, respectively, and the vessels and cooling bodies are moved relative to each other.
