Scandium is often associated with the rare earth elements . The ionic radius of Sc 3+ is slightly smaller than those of heavy REE for the same coordination number. During lateritic weathering of ultramaficmafic rocks, Sc behaves like the heavy REE. The enrichment factor of Sc between the ore and fresh saprolite is ca. 5 (Table S 5, Fig ...
Beneficiation Robert Gerhard Merker, Darren L. Smith Seltene Erden Aspekte des Marktes und der Aufbereitung Although varying definitions exists, it is widely viewed that the Rare Earth Elements are a group of elements of the periodic table of elements comprised of the 15 lanthanides and yttrium, although scandium is occasion
Scandium also exhibits exceptional electrical conductivity and heat stabilization qualities and the largest volume current use is in solid oxide fuel cells . Incorporation of scandium in SOFCs enables a lower operating temperature resulting in longer lived equipment and less costly materials of construction.
A study on the rare earth ore containing scandium by high gradient magnetic separation 625 As indicated in Table 6, the beneficiation results can be gained with using 1 , 2 , or 3 separately, indicating that the ore has strong adaptability to the magnetic matrix. The index of the combination of 1 and 3 was the best.
