摘要
介绍了利用有机还原剂处理银锰矿先浸锰后浸银新工艺的研究 ,锰的浸出率大于96 % ,银的浸出率大于 94 % ,并且银浸出时具有NaCN用量少、浸出时间短的特点。
The new technique with organic reducing agent for individual leaching Mn and Ag from silver-manganese ore are investigated in this paper. The recovery of 96% for Mn and 94% for Ag are obtained in respectively leaching, and extracting Ag takes fewer NaCN and time.
