Introduction. Rare earth elements (hereafter referred to as REEs) is a collective term for seventeen chemical elements in the periodic table consisting of yttrium (Y), scandium (Sc), and the 15 elements of the lanthanide series (IUPAC 2005). Despite the name, REEs are not very rare and found far more commonly in the Earth's continental …

Monazite is a red/green-brownish, waxy mineral. It is hard and resistant. Monazite is formed when igneous rocks undergo crystallization and when clastic sedimentary rocks undergo metamorphism. It is commonly mined in placer deposits, which are masses of loose sediment mainly consisting of sand. Minerals that are often found with or near ...
