A review of the beneficiation of rare earth element ...

(Trifonov, 1963). The difficulty in rare earth mineral exploitation is that the rare earth minerals are not commonly found in eco-nomic concentrations (Gupta and Krishnamurthy, 2005; Vijayan et al., 1989). Rare earth elements are never found as pure metals, instead they are found in a variety of minerals including silicates,

Germanium Statistics and Information

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. The development of the germanium
