The processes for rare earth (RE) extraction include the decomposition of RE minerals, and the concurrent or subsequent leaching of the rare earth elements (REEs) from the decomposed minerals. Ore beneficiation concentrate can be decomposed by, for example, acid roasting, caustic cracking, and chlorination. The REEs can be selectively extracted.
The rare earth market continued sluggish in 2016, with continuously falling prices and slow growth of downstream deep processing enterprises. The depression has lasted for five years. The "13th five year" Plan for Development of Rare Earth Industry, the first plan for rare earth .
A comprehensive review is presented of the extractive metallurgy of rare earths. The topics covered are: world rare earth resources and production; ore processing and separation of individual rare earths; reduction, refining, and ultrapurification of rare earth elements; methods for rare earth materials analysis; and a selection of the numerous rare earth applications.

1, radiation processing method The main advantage of the thorium content of the different rare earth minerals and gangue minerals in the ore, the use of the gammaray concentrator to separate rare earth minerals and gangue mineral.
1,Lead ore processing is in the beneficiation process on complex a tilt bed plane, ore particle swarm from the bed surface angle to the trough into, at the same time . mining equipment of gravity concentration, it is widely used in the selection of tungsten, tin, tantalum, niobium and other rare metals and precious metal ore .
Numerous European industries are heavily dependent on imported rare earth element (REE) raw materials. This has created a need for the European Union (EU) to ensure a sustainable supply of REE minerals, as well as develop from the ground up the currently nonexistent European REE extraction and processing industry.
