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. The residue, which contains the germanium, is leached with ...

Germanium improves cellular oxygenation. This helps to fight pain, keep the immune system functioning properly, and rid the body of toxins and poisons. Researchers have shown that consuming foods containing organic germanium is an effective way to increase tissue oxygenation, because, like hemoglobin, germanium acts as a carrier of oxygen to ...

Germanium is never found as a pure metal in nature, but trace amounts occur in many minerals, including common metallic ore minerals such as the zinc mineral sphalerite. Zinc smelters produce the …

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. ...

Both Sb-doped Germanium and Ge-Si solid solution single crystals with resistivity from 1.5 to 7 Ω·cm were grown using the Czochralski method. The optical transmission of single crystals and the ...

Gallium, germanium, indium, and other minor and trace elements in sphalerite as a function of deposit type - A meta-analysis July 2016 Ore Geology Reviews 76:52-78

To explore the source, migration, and enrichment mechanism of germanium (Ge) and the metallogenic model of the Wulantuga coal-hosted Ge ore deposits in the Shengli Coalfield, this study analyzed ...

Description: Abstract: This data release provides data for the single site in the United States (U.S.) that has public record of germanium (Ge) production. Germanium, …

Most germanium, is found in sphalerite (50-250 g/t); very little is present in other ore minerals, gangue minerals and the country rocks (less than 10 g/t). Fine grained germanite (?) is found in ...

Germanium Ore. Ore from the Pend Oreille Mine, which is known for having a particularly high germanium content. Source: eBay seller minclassixx Contributor: Theodore Gray Acquired: 2 April, 2009 Text Updated: 3 April, 2009 Price: $20 Size: 3" …

January 1, 1985. Germanium is enriched in the following geologic environments: 1. (1) iron meteorites and terrestrial iron-nickel; 2. (2) sulfide ore deposits, particularly those hosted …

These deposits host 60 million tonnes (t) at 100–200 parts per million (ppm) Ge and 28 million t at 50–150 ppm Ge, respectively. Currently, germanium is produced as a byproduct of zinc-bearing ore deposits. Acid mine drainage may have elevated signatures of germanium because of germanium's strong association to sulfide minerals (Shanks ...

Currently, germanium is produced as a byproduct of zinc-bearing ore deposits. Acid mine drainage may have elevated signatures of germanium because of germanium's strong association to sulfide minerals (Shanks and others, 2017). Germanium is also recovered from lignite and coal deposits worldwide (Melcher and Buchholz, 2014).

[citation needed] Early solid state electronics were based on germanium. The planet Alphard, the capital of the Marian Hegemony, has huge resources of germanium and is the source of the planet's wealth. The Federated-Boeing Interstellar Galax Megaplex has the largest known factory station: a germanium ore refinery massing more than 2 …

Germanium in coal is generally considered to be an organically bounded element, and the Ge enrichments in coal are mostly explained by the presence of Ge-ore bearing formations in the adjacent areas, penetration of hydrothermal solutions, or meteoric waters from granitic rock through fault zones (Arbuzov et al., 2021a, 2021b; Dai et al., …

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 …

Gallium occurs in many different minerals and rocks where substitution takes place with elements of similar size, such as zinc, or similar charge, such as aluminum. Therefore, Ga is primarily recovered as a byproduct of processing aluminum or zinc ores (Foley and others, 2017). Some U.S. zinc deposits contain up to 50 parts per million Ga, …

Germanium is a chemical element belonging to the carbon group of the periodic table. It can be found under the symbol Ge, with an atomic number 32, atomic mass of 72.59 g.mol-1, and electron configuration [Ar]3d 10 4s 2 4p 2.. Sharing the same group with carbon and silicon, this element is classified as a metalloid, i.e. a substance …

The Lincang germanium deposit, Yunnan, SW China, contains at least 1000 tonnes of Ge at an average grade of ~ 850 ppm Ge, and is one of the largest Ge deposits in the world.
