The research has been made on the characteristics of a copper-molybdenum ore,in which the distributions of chalcopyrite and molybdenite are uneven,so they are d ifficult to separate. In light of the fact,by adopting a reasonable reagent system and a processing flow consisting of the bulk flotation of copper and molybden um,the regrinding and three cleanings of mixed copper-molybdenum concentrate,the separation of copper and molybdenum,the three cleanings of molybdenum concentra te and one scavenging of copper concentrate,the good technical indexes of minera l processing such as the molybdenum concentrate grade of 41.02%,with recovery ra te of 62.41%,and the copper concentrate grade of 29.12%,with recovery rate of 81.10%,were achieved,result in the rational recovery of molybdenite and towanite.
