INDONESIAN REE, LITHIUM, AND GRAPHITE POTENCY

The rare–earth elements are, by definition, group composed of seventeen elements consisting of scandium (Sc), yttrium (Y), La and the 14 lanthanides Ce–Lu. The term ‘rare earth’ has often been applied in the more restricted sense as a synonym for the lanthanides, thus excluding Sc, Y and La. From lanthanum (La) to europium (Eu) are grouped into Light REE (LREE) while from gadolinium (Gd) to lutetium (Lu) are classified as Heavy REE (HREE).
