    摘要: Method and apparatus for separating and/or purifying a substance from a molten mixture by crystallization, in which the molten mixture is conducted into an annular space defined by two substantially curvilinearly-shaped surfaces, one of the surfaces being cooled, and at least one of the surfaces rotating. The molten mixture is thereby cooled as the same flows through the annular space with material crystallizing to form a deposit upon the cooled surface. The crystallized deposit is then caused to be contacted by a source of heat, whereby the same is melted. At least part of the melted deposit is then removed from the annular space, to obtain the substance in purified form, while any remaining part of the melted deposit is conducted through the annular space in a direction away from the source of heat. Non-crystallized molten material which contains impurities is also removed from within the annular space.
