Flotation of Sulphide Copper Ore of Sifangjing in Huidong

Abstract:

Flotation experimental research is carried out on a certain sulphide copper ore of Sifangjing in Huidong, Sichuan province. The ore exist in the deeper part of ore deposit. Because of the deep burried, the oxidation rate is relatively low. The ore belongs to the typical sulfide ore. For the characteristics of the mine and the scene of the test requirements, the use of direct flotation process has achieved a successful recovery of copper. In the cleaning operation ,Strengthen copper sulfur separation to obtain qualified copper concentrate. Under the proper process conditions ,the good technical indexes were obtained.
