PRECIPITATION OF NOBLE METALS FROM COMPLEX CYANIDE SOLUTIONS USING RED PHOSPHORUS PLUS OX. AGENT |
| 摘要 |
<p>Noble metals are recovered from their cyanide complexes in aqueous solution by reaction with red phosphorus. To this end, red phosphorus is used in quantities of 1 to 5 weight %, based on the aqueous solution of the noble metal cyanide complex, in combination with an additional strong oxidizing agent.</p> |
