| Abstract: | The gold extraction recovery from Zhenyuan arsenic and antimony bearing carbnous concentrate with cyanide leaching process is less than 10%, and it can be raised to 73.2% with roasting-cyandiation process. The gold recovery can be improved further to 90.4% with antimony removal with sodium sulfide, followed by roasting and cyanide leaching process. The antimony concentrates can be sold as by product. |
