germanium ore process

Germanium Statistics and Information USGS

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

Germanium: Current and Novel Recovery Processes IntechOpen

Jan 22, 2018· Germanium (Ge) is considered a critical element due to its many industrial applications; Ge is a metalloid used in solar cells, fiber optics, metallurgy, chemotherapy, and polymerization catalysis. The main sources of Ge are sulfides ores of Zn, Pb, and Cu, coal deposits, as well as by-products and residues from the processing of these ores and coals (e.g., smelting flue dust and coal fly ashes).

Germanium Properties, History and Applications

Jun 25, 2019· Regardless of the source of material, all germanium concentrates are first purified using a chlorination and distillation process that produces germanium tetrachloride (GeCl4). Germanium tetrachloride is then hydrolyzed and dried, producing germanium dioxide (GeO2). The oxide is then reduced with hydrogen to form germanium metal powder.

Germanium an overview ScienceDirect Topics

F.A. D’Altroy, in Encyclopedia of Materials: Science and Technology, 2001. 1 Technology. Germanium does not appear in commercial quantities as a native ore but is produced principally as a by-product of zinc processing, with a smaller amount from the processing of copper. The germanium-containing metallic zinc is first distilled under nonoxidizing conditions.

[Ar]4s 3d 4p USGS Mineral Resources Program Germanium

Germanium is a semiconducting metalloid with electrical properties between those of a metal and an insulator. Germanium was discovered in the late 1800s within silver ore at a mine near Freiberg, Germany. The German chemist who described the element, Clemens Winkler, named it germanium, after his native country.

He isolated the new element from the ore and named it germanium, in honor of Winkler's native country, Germany. Winkler discovered that the properties of germanium were very similar to those that Mendeleev had predicted 15 years earlier. For example, Mendeleev thought element 32 would have a density of 5.5 grams per cubic centimeter.
