Recovery of Rare Earth Elements and Critical Materials from Coal
Significant progress has been made toward enabling commercial production of CMs in addition to the work establishing commercial production of REE from unconventional sources. Production of many CMs and REEs needed for the processing of battery materials, such as cobalt, lithium, and gallium, from coal-based sources appear promising.At 95 °C, 99% rare earth metals were recovered in 3 h using 4 mol dm 3 HCl. Later, rare earth metals were extracted using 25% D2EHPA at pH 2.5. Tzanetakis and Scott (2004). Sulfuric acid.
