Gold-bearing ore processing technology

Gold ores containing antimony have often associated arsenopyrite and pyrite, this mineral is a complex of antimony important types. It has greater economic value than a single antimony ore. Gold exists in the microscopic and submicroscopic natural gold in the ore. It is embedded in stibnite, arsenopyrite and pyrite. Most of the gold ore in China belongs to this type. At present, there is no ore dressing method to completely separate the strontium and gold in the bismuth gold ore. Most of them are recycled by the combined process of smelting and smelting. The following is a summary of the domestic and foreign treatment of gilt ore or the research that has been studied and considered effective. Process: blast furnace volatile smelting - ruthenium electrolysis process; oxidative roasting - reduction smelting process; medium temperature roasting - caustic soda solution leaching - cyanide gold extraction process; sodium sulphide solution leaching - electrolysis sputum - cyanide gold extraction process. Hunan Xiangxi gold mine gold using antimony smelting blast furnace volatile - expensive antimony electrolysis process, after years of practice has been more mature, its process flow shown below.
