Application of Chelating Collectors in the Flotation of Copper Minerals

摘要

The application of new chelating reagents on the flotation of copper minerals has been paid much attention in recent years. These collectors have successfully extracted the copper minerals from the low-grade refractory ores, and one of the most important collectors is the alkylhydroxamate-based chelating reagent which shows the excellent flotation performance to the copper oxide minerals. Furthermore, the mixture of various chelating reagents can recover the copper sulfides and oxides simultaneously from the complicated copper ores, which is attributed to the synergy among collectors. Thus we conclude that it is an important flotation method by using chelating collectors in conjunction with other traditional collectors, by which the synergy can break through the limitation of single reagent and enhance the flotation efficiency.
