In the U.S., germanium was also recovered as byproduct of zinc mining and refining in Tennessee, as well as recycled from industry-generated scrap at a refinery in Oklahoma. "Based on an analysis of zinc concentrates, U.S. reserves of zinc may contain as much as 2,500 tons of germanium," USGS inked in its 2022 Mineral Commodity …
This section assesses Australia's resource potential for selected critical commodities. In Table 1.5.1 the key results of this review are summarised in two groups of commodities: those with category one resource potential and those with category two resource potential. These are extracted from Table 1.5.2 which presents a more comprehensive ...
Most germanium is recovered as a byproduct of zinc ore (sphalerite) processing, and occasionally from silver, lead, and copper ores. ... U.S. reserves of zinc may contain as much as 2,500 tons of germanium, but because zinc concentrates are shipped globally and blended at smelters, the recoverable germanium in zinc reserves …
Most Germanium is recovered as a byproduct of zinc smelting, but it has also been recovered at some copper smelters and from the fly ash of coal-burning industrial powerplants. Around half of total known resources are located in Russia and one quarter is located in China. The world average production of refined germanium is dominated by …
A major source of germanium recovery and also the source of this research is the by-product of lead and zinc metallurgical process. The primary purpose of the research is to investigate the ...
A major source of germanium recovery and also the source of this research is the by-product of lead and zinc metallurgical process. The primary purpose of the research is to investigate the effects of ultrasonic assisted and regular methods on the leaching yield of germanium from roasted slag containing germanium.
Germanium is a fairly rare element that is found in the Earth's crust. Although there are some minerals that contain a fair amount of germanium like germanite and argyrodite, they are too rare to be mined. The majority of germanium that is used by industry is produced as a byproduct of mining sphalerite zinc ore where it is found in small traces.
Germanium ores are rare and most germanium is a by-product of zinc production and from coal fly ash. China produces around 60% of the world's germanium, according to European industry association ...
Germanium is recovered as a byproduct of zinc (Zn) sulfides, and mining and processing of these materials lead to waste that could act both as a source of extractable Ge and a source for exposure to humans and ecosystems. Yet the distribution, speciation, and mineral hosts of Ge in mining-impacted areas are poorly understood. ...
Germanium occurs as a byproduct in deposits of copper, gold, lead, silver, and zinc and is associated with ores of mineral sulfides, oxides, hydroxides, …
Germanium is always extracted as a byproduct during the ongoing processing of sphalerite zinc ore, fly ash coal, and some copper ores. In the case of sphalerite zinc ore roasting, the entire ore is transformed into germanium oxide, which further gets reduced by carbon to produce germanium. (GeO_2 + C → Ge + CO_2)
Germanium output is centered at the zinc-lead plant of Balen, Belgium, where it is a byproduct of electrolytic zinc. A pioneer of germanium as well as Europe's oldest and largest producer of zinc is Vieille-Montagne.

In North America, germanium is recovered alongside zinc, lead and other metals at Teck Resources Ltd.'s Trail smelter in British Columbia. Other producers include specialty materials maker 5N ...
Leaching of the dross containing 28.7% Sn, 18.0 Pb, 10.6% Cu, 8.9% Ge, 8.1% Zn, and 2.7% In in sulphuric and oxalic acid solution was investigated. The dross was obtained from thermal oxidation of by-product alloy …
China said on Monday it will impose export restrictions from Aug. 1 on some gallium and germanium products, metals used in computer chips and other products, to protect national security interests. China produces around 60% of the world's germanium, according to European industry association Critical Raw Materials Alliance (CRMA), with …
Gallium is conventionally obtained as a byproduct of aluminum, and germanium as byproduct of zinc processing. An exception to this rule is the Apex Mine ore which has served as the only primary source in the world for direct production of gallium and germanium. In addition, the solvent extraction and bioleaching possibilities of these …
Germanium (Ge) is a metal used in emerging energy technologies, communications, and defense, and has been deemed critical by the United States due to its essential applications and scarce supply. Germanium is recovered as a byproduct of zinc (Zn) sulfides, and mining and processing of these materials lead to waste that could act both as a source of …
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 …
The extraction efficiency of germanium from zinc concentrate treated by hydrometallurgy is about 68%. There is therefore a large amount of potentially …
The main sources of germanium are zinc refinery residues and fly ash, and thus its production increase depends on the motivation of zinc refineries and coal power plants to engage in the germanium market [8]. ... Germanium occurs as a byproduct in deposits of copper, gold, lead, silver, and zinc and is associated with ores of mineral …
Abstract A 2015 Life Cycle Assessment (LCA) study on germanium included the sourcing from fly ashes from coal combustion and its recycling from photovoltaic production scrap. Germanium is also produced as a byproduct from zinc production, typically present at levels above 75 ppm in zinc ores, and this is the second globally …
Similar germanium solar cell technology is also slated to power NASA's Gateway space station currently under development. Germanium also boasts superior optical properties that are widely used in fiber optic cables and night vision goggles, applications that have traditionally been the primary driver of demand for this zinc …
The price relationship between lead-bismuth, lead-selenium, zinc-germanium, and zinc-cadmium has been studied in the literature (Kim and Heo, 2012; Shammugam et al., 2019; Afflerbach et al., 2014). The premise of this previous work, however, is that there is only a one-way Granger causal relationship between the main …
