Separation of rare earth elements from contaminants

01/06/2020· For commercial purposes, rare earth elements (REEs) are obtained from concentrates with a rare earth oxide (REO) content of about 60 wt% . Absolute concentrations and ratios of REEs to other elements in leach liquors are accordingly high. Remaining impurities can be removed, for example, by neutralization prior to the separation of individual REEs. On the other hand, by leaching low-grade raw

New Rare Earth Element Extraction Technology

The MOF outer layer carries molecules that are attrac­tive to rare earth elements, causing the elements to stick to the nanoparticle. Using this method, the brine is then passed through a magnetic separator to remove the nanoparticles contain­ing rare earth elements. The now nanoparticle-free brine is recirculated to recover more rare earths from the geothermal fluids. What’s more, PNNL
