Abstract:The copper and cobalt content in the Congo (gold)S copper and cobalt ore is 1.70% and 0.291%, respectively. The oxidation rate of copper and cobalt is up to more than 90%, and it has the characteristics of high calcium magnesium, low iron, poor sulfur and high content of buoyant gangue. A kind of high-efficiency activator -- CCMA811 was developed for this type of ore. The mixed concentrate of copper and cobalt was obtained through the process of "grinding -- easy floatation -- sulfuric oxygen mixed flotation", in which copper 24.97% and cobalt 3.22% were contained, and the recovery rates of copper and cobalt were 79.02% and 60.59%, respectively, realizing the efficient recovery and utilization of copper and cobalt resources.
