Beneficiation of rare earth minerals from Bokan Mountain

The purpose of this research work was to study the beneficiation of rare earth ore of the Bokan Mountain Dotson Ridge deposit located near Ketchikan Alaska. Rare earth element (REE) composite ore samples from the Bokan Mountain Dotson Ridge deposit were tested using gravity concentration magnetic separation flotation and leaching techniques to separate the REE.

Process mineralogy of Dalucao rare earth ore and design of

The test results of the automated mineral identification and characterization system (AMICS) including the mineral composition particle size distribution dissemination state and degree of liberation of the target minerals could be used to improve the beneficiation process. Taking the Dalucao rare earth ore located in Dechang Sichuan Province China (with an average content of

A review of the beneficiation of rare earth element

Highlights Review conducted of RE mineral beneficiation using English and Chinese language sources. Of the 250 known RE minerals only bastnäsite monazite and xenotime are extracted commercially. Flotation using fatty acids or hydroxamates is the primary separation process for RE minerals. Currently optimal beneficiation processes employ flotation gravity and magnetic separation.

Rare Earth Beneficiation and Hydrometallurgical Processing

Prior to individual REE separation the rare earth ore will go through a series of physical separation and hydrometallurgical processing. In this chapter the rare earth ore beneficiation mineral
