Processing the ores of rare-earth elements | MRS Bulletin
Geology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rare-earth minerals are monazite and bastnäsite (Figure 1a–b and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REE-bearing monazite is a complex phosphate. 5 Bastnäsite, …
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.
Definition, Methods of Separation, Examples
On passing the ore via an upward stream of water, the lighter gangue particles are separated from the heavier metal ore. This is a gravity separation method. This process is used to enrich ores that are heavier than the gangue particles that are present in them. A stream of water is run through crushed and finely powdered ore in this …
