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
Some zinc-copper-lead ore bodies contain enough germanium to justify extraction from the final ore concentrate. An unusual natural enrichment process causes a high content of germanium in some coal seams, discovered by Victor Moritz Goldschmidt during a broad survey for germanium deposits.
The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use.

A process to increase the content of germanium which is found in an iron hydroxide phase of an ore of the supergene type for later recovery by solvent extraction. The process comprises the steps of first crushing the ore, converting the ore to pulp, and then subjecting the pulp to a magnetic separation to give a magnetic fraction enriched in germanium.
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.
Hydrothermal process is the most common ore forming process. Water is heated by the magma chamber and this water dissolves metals. Metals are dissolved in the water and this solution seeps through cracks, fractures and through permeable rocks until they are precipitated and form a deposit. There are three types of water sources
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 ...

Jun 30, 2019· As these uses of iron ore illustrate, rocks containing some percentage of iron have a broad variety of industrial applications. Mining of iron ore worldwide is an extremely large industry and it is one of the most valuable commodities because of its myriad uses and the high demand for products like structural steel.
The germanium production process yields various germanium compounds and metal for use in specific applications. Germanium is initially recovered through the leaching of zinc-refining residues or coal ash, followed by precipitation of a germanium concentrate from the leachate. The concentrate, regardless

It is a lustrous, hard, Today, germanium is mined primarily from sphalerite (the primary ore of zinc), though germanium is also recovered commercially .. Get Price
Ore store is an ore speciality store located in south-west Jatizso.It shares a building with the Armour Shop, which specialises in mithril armour. The shop-owner is Hring Hring.As the Ore Store stocks ore, it is highly likely that the metal Armour Shop uses to smith their weapons is obtained from there.
Vanadium processing: Vanadium processing, preparation of the metal for use in various products. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to high-strength
The process of extracting tin from tin ore varies according to the source of the ore deposit and the amount of impurities found in the ore. The tin deposits in Bolivia and England are located deep underground and require the use of tunnels to reach the ore. The ore in these deposits may contain about 0.8-1.0% tin by weight.
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.
Zinc processing: 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. It has only moderate
Aside from ore, gallium can be obtained from such industrial sources as the Bayer process caustic liquor that is a byproduct of bauxite processing, flue dust removed from the fume-collection system in plants that produce aluminum by the electrolytic process, zinc refinery residues, gallium scrap materials, and …
Source: The main ore of germanium is germanite, which is about 7% germanium. Commercially, germanium is obtained as a byproduct of metal refining and from some coal ashes. Isotopes: Germanium has 24 isotopes whose half-lives are known, with mass numbers 58 to 85.
