Improved understanding of rare earth surface chemistry and its application to froth flotation
MetadataShow full item record
The United States contains a variety of domestic rare earth element mineral sources containing bastnasite, monazite, and xenotime. This research was performed to investigate the fundamental surface chemistry involved in the froth flotation of these minerals, and apply the knowledge gained to substantiate the results through experimental testwork on a domestically sourced rare earth ore. Electrokinetic studies were performed to establish the potential determining ions for all minerals. An extensive study on the effect of various activators (Co2+, W6+, Cr3+, Mo6+, Fe2+, Al3+, Cu2+, Pb2+, and ...
