| Abstract: |
| Three methods: hydrochemical oxidation; cyanidation-hydrochemi-cal oxidation and acid FeCl3 leaching of silver-chlorination of gold, have been studied by the authors for the treating carbonaceous silver concentrates. Some problems such as carbonaceous substances affecting the extraction of gold and silver and the reuse of leaching agents have been investigated and effective techniques recommended. By using these methods,94%-99% silver extraction and 88%-95% gold extraction were obtained. |
