Thus, germanium is found in argyrodite (a sulfide of germanium and silver, (Ag 2 S) 4 Ge·Se, containing 5–7% of germanium), germanite (a copper–iron–germanium sulfide, 7CuS·FeS·GeS 2, containing 8.7% of germanium), zinc ores, certain coals, and other minerals. Germanium is also found in soil, water, plants, and animal bodies.
The invention provides a process for recovering germanium as germanium oxide from a germaniferous metallic zinc which involves distilling the germaniferous metallic zinc under non-oxidizing conditions, recovering the distillation residue which contains the germanium, leaching the recovered distillation residue with chlorine water to convert the germanium into germanium tetrachloride ...

Germanite is a rare copper iron germanium sulfide mineral, Cu 26 Fe 4 Ge 4 S 32.It was first discovered in 1922, and named for its germanium content. It is only a minor source of this important semiconductor element, which is mainly derived from the processing of the zinc sulfide mineral sphalerite. Germanite contains gallium, zinc, molybdenum, arsenic, and vanadium as impurities.
of 24 parts per million (ppm). Germanium is known to replace zinc in the sphalerite (zinc sulphide) lattice in some zinc ore bodies and is generally observed, where mined, to report to the processed zinc concentrate where the grade is likely to increase pro-rata with the zinc grade. In the Citronen project the zinc is generally upgraded between ...
Germanium is mainly a byproduct of zinc ore processing.It is a hard, grayishwhite element it has a metallic luster and the same crystal structure as diamond.Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.Germanium is an important semiconductor, mainly used in transistors and integrated circuits.
germanium (Ge) supply is primarily dependent on zinc mining as it is produced as a by-product from zinc ore and is not mined as a primary material recycling is an important source of Ge supply; about 30% of the world's total production of germanium is from recycled material
The sulfide- poor "oxidized" zinc ore (up to 50 wt.% Zn; 250 to Germanium (Ge) is an important high-technology electron- 300 ppm Ge) is a fine-grained, often friable, alteration ic metal, as it is used in the manufacture of semiconductors, product of the sulfide ore and associated limestone and solar panels, fiber and infrared optics, and
and the particle size of the zinc concentrate are shown in Table 1 and 2, respectively.

Sep 18, 2018· Germanium is produced almost exclusively from waste residue of hydrometallurgical zinc processing operations (Llewellyn, 1989). Currently, high-grade domestic zinc residues containing enough germanium to supply the annual needs of the U.S. are processed in foreign countries by proprietary techniques to recover the germanium (Plunkert, 1985).

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.

from the zinc ore mineral, sphalerite (zinc sulfide). Because metallurgical operations are commonly fed by concen-trates from multiple deposits and diverse locations, it is difficult to track germanium production to specific deposits. It has been estimated that less than 5 percent of the germanium contained in zinc concentrates is recovered.
Germanium. Germanium is a rare semi-metal that is extracted from residues of sphalerite zinc ore and lignite coal deposits. Less than 200 metric tonnes of germanium are refined globally each year. The most commonly available forms of germanium are zone-refined ingots and germanium dioxide (GeO2).
