Rare-earth element - 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 andor electrostatic separation and flotation.
Because of low grade of thorium and uranium in the Zarigan mineral deposit, the pre-concentration operation prior to leaching is necessary. From X-ray diffraction analysis results, it was clear that this ore has large amount of other minerals such as Feldespat, Qua

Jan 15, 2012 Composite chitosan magnetic particles prepared by an original method were evaluated as a new radiocation adsorbent. The material has superior adsorption capacity both for uranyl 667 mgg and thorium 313 mgg ions. Radiocation adsorption is spontaneous and endothermic Both ions may be recovered to the extent of over 80. This adsorbent is a good low-cost candidate for applications in
Abstract. A study is made of three processes for the separation of thorium from uranium and rareearth elements in crude thorium nitrate solutions prepared by breakdown of monazite sand. Uranium may be separated from thorium and rareearth elements in a preliminary extraction with 5 or 40 vv trinbutyl phosphate TBP in xylene and the thorium separated from the rareearth elements in a
Removal of Iron and Titanium from the Manganotantalite and Ferrotantalite Samples in this Study was Successfully Accomplished by Magnetic Separation. Acid Leaching Using H2SO4 on the other Hand Removed a Large Portion of Thorium and Uranium in these Samples.

Feb 09, 2018 Separation of Monazite Sands . Monazite sands are natural accumulations or concentrations which carry thorium and cerium oxides as their valuable constituents, together with garnet, menaccanite, rutile, zircon, and other heavy minerals as contaminations. The sand is usually concentrated by washing and the concentrate separated on magnetic separators.

Current magnetic separation technologies either employ a magnet attached to the side of a small tube, or a small tube with a magnetizable mesh inside. In the latter case, when a magnetic field is applied, the mesh becomes magnetized, trapping the particletarget components. However, there are significant limitations to both of these approaches.
