| Abstract: | The gold extraction recovery from refractory gold concentrate with As and Sb content using cyanide leaching process is only 42.79%, and it can be raised to 48.22% using roasting-cyandiation process. The gold recovery can be improved further to 86.3% by antimony removing with sodium sulfide, followed by roasting, milling and cyanide leaching process, while antimony removal rate reached to 96.6%, antimony can be sold as by-product. |
