Title:
NOBLE METAL ADSORBENT USING COPPER SMELTING SLAG AS RAW MATERIAL, AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2012001747
Kind Code:
A
Abstract:
To provide a noble metal adsorbent which uses magnetite in slag produced in copper smelting as a raw material, and to provide a method for producing the same.
The method for producing the noble metal adsorbent includes providing slag produced in copper smelting as a raw material, and successively subjecting the slag to (i) a grinding step, (ii) a classification step, and (iii) a concentration step by magnetic concentration method, thereby separating the adsorbent containing magnetite in the slag. The noble metal adsorbent is obtained by the production and is used for recovery of noble metals in a wet smelting step, or recovery of noble metals from fine particle-containing sludge.
