| Abstract: |
| Gold ores containing arsenic is a typical refractory gold resource. It also is one of the important gold types in our country. A few of extracting technology was reviewed, including roasting oxidation process, bacterial oxidation process, flotation separation process, non-cyanide leaching process and so on. The advantages and disadvantages of each technology and its application were also discussed. The development direction and research focus were summarized. |
