Specifications:
Preparation:
The mixed rare earth obtained by decomposing the ore by extraction method is fed with the rare earth nitrate solution after removing cerium, and the yttrium-rich rare earth is extracted and grouped to obtain the yttrium-rich rare earth. After acid dissolution, the yttrium is extracted and purified. Into the organic phase, and then through thulium and lutetium group extraction and back extraction, so that thulium and ytterbium enter the water phase, and are separated by oxalic acid precipitation, filtered and burned to obtain thulium oxide.
