Rare-earth element - Processing ores Britannica

The best way to affect the separation of the rare earths is to use a multistage counter-current extractor on a continuous flow basis using many mixer-settler tanks or cells. For the case in which A has greater affinity for the organic phase and B has greater affinity for the aqueous phase, the organic phase becomes enriched in A and the aqueous phase enriched in B.

28/06/2020  However, seen from the degree of liberation, the intergrowth of the rare earth ore and feldspar, as well as calcite, quartz, fluorite and biotite was severe. Gravity separation would lead to a low yield of rare earth, and high-grade minerals cannot be obtained if only magnetic separation was used. Therefore, the Dechang Dalucao ore was beneficiated by both gravity separation and magnetic

Processing a rare earth mineral deposit using gravity

Magnetic separation is used primarily to remove ferromagnetic gangue minerals as well as to separate individual paramagnetic rare earth minerals. This work investigated the use of a wet high intensity magnetic separation (WHIMS) in conjunction with gravity pre-concentration steps (Knelson and Falcon centrifugal concentrators) to beneficiate a rare earth ore.
