Document Type and Number:

Japanese Patent JP5415066

Kind Code:

B2

Abstract:

To provide a metal refining method and apparatus, etc., by which the refined metal weight can be increased by preventing the metal crystallized under state of high solidified speed from being exfoliated from a cooling body in the initial stage of the refining.

In the method for refining the metal, crystallizing a high purity metal on the cooling body surface while rotating this cooling body 3, by dipping the cooling body 3 into molten metal 2 to be refined; the average rounding speed of the cooling body 3 at the initial stage of the refining, is set at lower than the average rounding speed after the initial stage and the refining is performed by setting so that the maximum rounding speed of the cooling body 3 at the initial stage of the refining is not exceeded to the average rounding speed after the initial stage.
