Rosatom’s Mining Division has developed a technology for the separation of collective rare earth metal (REM) concentrates. This will fill in the missing link in the technological chain of rare earths production.
Production is planned to be organised at the Solikamsk Magnesium Plant (SMZ), which together with the Lovozersky GOK (supplier of raw materials to SMZ) recently became part of the state corporation’s mining division.
“Rosatom’s mining division extracts loparite ore and enriches it at Lovozersky GOK, and then the loparite concentrate is sent to Solikamsk. Here we isolate niobium, tantalum and titanium, while other important rare earths (lanthanides) remain in the collective concentrate,” explains SMZ general director Ruslan Dimukhamedov.
The essence of the technology is to dissolve the concentrate remaining after the isolation of a number of rare earth metals in nitric acid. The result is a nitrate solution of rare earths. Cerium is extracted from this solution by electro-oxidation and subsequent extraction. From the remaining solution, other rare earth elements are removed sequentially by extraction separation. The process involves precipitation, drying, and calcination.
According to Ruslan Dimukhamedov’s recent interview with Monocle magazine, the technology’s development started a year and a half ago, before SMZ and Lovozersky GOK joined the Rosatom group.
A pilot plant has been constructed, with a yearly output of one and a half tons of rare earth metals.
The technology is now being scaled up, and a separation complex is being designed at the SMZ site. Production is scheduled to begin within the next two to three years.

Incredible!
I make more then $13k a month online. It’s enough to comfortably replace my old jobs income, especially considering I only work about 11 to 12 hours a week from home. I was amazed how easy it was after I tried it….

Putin posing topless. Where is his self-respect and dignity?
Read an article yesterday about a new, very simple, cheap, process invented/deduced by a uni(?) in the West in which they run the rare earth soup obtained from old phones & batteries over a gel, to which the various metals adhere in a sequence according to atomic weight(?) or other unique characteristic. Similar to fractional distillation to separate the different carbon compounds in crude oil
Easy, simple, cheap.
