Rare-earth element - Processing ores | Britannica

Rare-earth element - Processing ores: All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.rare earth froth flotation - yachtprotect,A process and flotation agents are provided for flotation of lead-, uranium-, and rare earth-type minerals and ores in which an aqueous pulp of the mineral or ore is subjected to a froth flotation, characterized in that the flotation is performed inRare Earth Flotation Fundamentals: A Review - AJER,Rare Earth Flotation Review Literature on the flotation of rare earth oxide minerals is a relatively limited. This is especially true with regard to fundamental flotation research, although, as the demand for rare earths continues to grow, the amount of research in the field is increasing rapidly.
