Research Progress of Collectors and Flotation Mechanism for Rare Earth Mineral
The effective recovery and comprehensive utilization of rare earth elements have been a research fo-cus of rare earth beneficiation,of which foam flotation is the most widely used method.One of the hottest areas of study in rare earth flotation is the development and utilization of new-type collectors.In this paper,mineral-type rare earth flotation collectors around the world are described from the aspects of molecular structure,func-tional group characteristics,mechanism of interaction with minerals,and their flotation performance is further summarized.Furthermore,the current synthesis and research development of novel collectors are reviewed,as is the future study of rare earth flotation collectors.
