<p><P>PROBLEM TO BE SOLVED: To provide a method for refining a metal by which a metallic refined material having a composition of low content of impurity and no inclining constitution can continuously be obtained from a metal containing eutectic impurity. <P>SOLUTION: The method includes the following (a)-(b) processes. (a) Primary crystal is generated from the above molten metal in a vessel for generating a first semi-solidified slurry (hereafter, a slurry-generating vessel) to obtain the semi-solidified slurry (hereafter, the slurry), and the primary crystal integrating material (metallic refined material) is formed and recovered by supplying the above slurry to a vessel for first compression (hereafter, a compressive vessel) and also, a liquid phase in the first compressive vessel is supplied to a second slurry-generating vessel and thereafter, a series of operations from the above same slurry supply, is repeated. (b) From the liquid phase supplied to the second slurry-generating vessel, the slurry is generated and supplied to a second compressive vessel to form and recover the primary crystal integration material. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
