Extraction of Rare-Earth Elements from Iron-Rich Rare-Earth …

Separation of iron and rare earths is theoretically possible by carbothermic reduction and could be used as an alternative to physical upgrading of the ore. As shown in the Ellingham diagram for pure oxides in Figure 1, iron oxide can be selectively reduced over rare-earth oxides; however, in the present case, smelting would be required to enable efficient separation of iron metal from REO-bearing slag. REO are stable under the iron smelting conditions generally described by the temperature and oxygen partial pressure, therefore they will report to the slag phase whilst the iron will report to the metal phase. Although this separation …
