<p><P>PROBLEM TO BE SOLVED: To provide a method for making moisture adhering magnesium alloy waste safe and recovering magnesium alloy waste by melting and refining the magnesium alloy waste made safe. <P>SOLUTION: The method for making the magnesium alloy waste safe includes (i) a step (a first step) of recovering the magnesium alloy waste (A) into an aqueous solution (B) for recovery, (ii) a step (a second step) of subjecting the aqueous solution (B) for recovery to a filtration and dewatering operation to obtain a solid content (C) including 30 mass% moisture, and (iii) a step (a third step) of immersing the solid content (C) into (D) a hydrophobic organic solvent (D), then removing a part of the solvent to obtain the magnesium waste (E) which includes 5 to 30 mass% hydrophobic organic solvent (D) and is made safe. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
