| Abstract: | Some problems in the mineral processing process was put forward and the corresponding techniques such as controlling overload of grinding and crashing, improving size and increasing flotation time etc were dealed with in this paper by the author. Through the reconstruction the flotation and cyanidation are more efficient than before. The flotation recovery is increased 1.43%, and the cyanidation recovery is increased 0.55%, at the same time the agent and energy consumption are decreased for some extent. |

| Keywords: | flotation concentration cyanidation gold recovery |
