| Abstract: | Mineral processing technology study was carried out on a Inner Mongolia refractory gold ore which micrograined-disseminated and easy to be slimed. The results showed that adopting a technological processes with stage grinding, discarding tailing via gravity concentration and stage flotation, a gold concentrate with gold content and recovery of 68.12 g/t and 81.31% can be obtained. Cyanide leaching of flotation tailings can further improved the total gold recovery. |

| Keywords: | gold ore stage flotation discarding tailing via gravity concentration cyanide leaching |
