Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre.
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.

Because there are no real germanium minerals the overall production process is always divided into two steps: production of germanium concentrate and the production of germanium. As described in the previous section the two main sources are zinc ores and coal.

Germanium minerals are also present in zinc ores, and commercial production of germanium is carried out by processing zinc smelter flue dust. It can also be recovered from the by-products of combustion of certain coals.
The ore concentrates are mostly sulfidic; they are converted to the oxides by heating under air in a process known as roasting: GeS 2 + 3 O 2 → GeO 2 + 2 SO 2 Some of the germanium is left in the dust produced, while the rest is converted to germanates, which are then leached (together with zinc) from the cinder by sulfuric acid.

This same behavior was observed in the leaching of germanium from zinc processing residues (Harbuck, 1989). Pugh (1929), in studying the GeO2-H2SO4 system at 25°C, Figure 2, found that as the sulfuric acid concentration increased, germanium concentration in solution decreased. (It should be noted that the dissolution of GeO2 is a slow process. Each data point in Figure 2 required 8 to 10 …
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). The Bureau of Mines, in an effort to enhance ...

Today, germanium is mined primarily from sphalerite (the primary ore of zinc), though germanium is also recovered commercially from silver, lead, and copper ores. Elemental germanium is used as a semiconductor in transistors and various other electronic devices.
The element is commercially obtained from the dusts of smelters processing zinc ores, as well as recovered from combustion by-products of certain coals. A large reserve of the elements for future uses in insured in coal sources. Germanium can be separated from other metals by fractional distillation of its volatile tetrachloride. The techniques permit the production of germanium of ultra-high ...
