VALUABLE METAL LEACHING METHOD, AND VALUABLE METAL COLLECTION METHOD EMPLOYING THE LEACHING METHOD |
摘要 |
The present invention provides a valuable metal leaching method and a valuable metal collection method, in each of which valuable metals can be leached efficiently, the amount of a reducing agent used can be reduced, and cost reduction can be achieved. In the present invention, a positive electrode material is immersed in an acidic solution together with a metal having a lower reduction potential than a reduction potential of hydrogen, whereby valuable metals are leached out from a positive-electrode active substance. |
