Rare-Earth Products

The need in various types of rare-earth products is existing and increasing. The development of the full production cycle- from raw material to the final products - became in Russia the task of paramount importance.
Rare-Earth Products This is the reason of establishing and functioning at ChMP within the bounds of conversion programme the production of the following types of rare-earth products:      
rare-earth carbonates;
light rare-earth oxid concentrate; 
Polishing powder on the base of rare-earth oxides.
This is the reason of establishing and functioning at ChMP within the bounds of conversion programme the production of the following types of rare-earth products:   
  • rare-earth carbonates;
  • light rare-earth oxid concentrate;
  • Polishing powder on the base of rare-earth oxides.
  • Rare-earth carbonates   
    Grade A - fine-dispersive crystallic powder, white or grey with tints from yellow to brown, representing the solid solution of light rare-earths.   
    Grade B - wet white paste with grey or brown tint representing water suspension of mixter of light rare-earth carbonates.
