METHOD FOR RECOVERING NOBLE METAL |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a method for efficiently recovering a noble metal without using acid having high oxidizing power. <P>SOLUTION: This invention relates to the method for recovering the noble metal from a base material containing the noble metal. The method includes: a step (S11) in which noble metal grains 12 on the base material 10 are subjected to chlorination treatment, so as to form a noble metal chloride; and a step (S20) in which the noble metal chloride or a compound containing the noble metal chloride is extracted from the base material 10. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
