Sunt rara terra metalla et mineralia?

Rara terraest metallum. Rare terra est a terminus ad XVII metallum elementa in periodica mensa, inter Lanthanide elementa et scandium et yttrium. Sunt CCL genera rara terris mineralibus in natura. Primus qui inventa rara terra erat Finnish Chemist Gadolin. In MDCCXCIV, qui separavit primam quaedam rara terra elementum a more aureis similis bituminis.

Rara terra est collective terminum ad XVII metallicum elementa in periodica mensa chemical elementa. Sunt lux rara terraeLanthanus, Cerium, Praseodymium, Neodymium, Promethium, Samarium et Europium; Gravis rara terra elementa: Gadolinium, Terbrium, dysprosium, Holmium, Erbium, Thulium, Yterpium, Lutetium, Scandium et YTTRIUM.Rara terrarum esse ut mineralia, ita sunt mineralia magis quam solo. Sinis est ditissimus rara terra subsidiis, maxime intenti in provinciis et civitatibus ut interiorem Mongoliam, Shandong, Sichuan, Jiangxi, Medium et gravibus rara terra est maxime praestantissime.

Rara terrae in rara terra concentrat plerumque in forma insolubilis carbonates, fluorides, phosphates, oxides, aut silicarium. Rare earth elements must be converted into compounds soluble in water or inorganic acids through various chemical changes, and then undergo processes such as dissolution, separation, purification, concentration, or calcination to produce various mixed rare earth compounds such as mixed rare earth chlorides, which can be used as products or raw materials for separating single rare earth elements. Hoc processum dicitur rara terra incumbo compositionem, etiam notum est pre-curatio.
