The paper presents the results of pilot tests of scandium extraction technology from uranium-rare-earth phosphorite to obtain high-purity scandium oxide Sc₂O₃. It is shown that scandium in phosphorites is accompanied by thorium and rare earth elements (REE), which requires the development of a techn...
