| 简介 |
The disclosure describes a method of extraction for optimal recovery of rare earth elements (REE). This includes the optimization of a liquid-liquid extraction technique for economic extraction of REE from chemically complex brines. Through the use of a model, operating conditions are altered to increase separation efficiency. The technique achieves >98% recovery of all rare earth elements in one fraction, while using small volumes of sample and reagents. The method of the present invention recovers REE from previously unexploited waste streams, without need for development of new process equipment and while keeping a small footprint because of the volumes involved. |
