Germanium

Gunnar Occurrence and Uses Germanium (Ge) is always found in combination with other elements and never in the free state. Among the most common germanium-bearing minerals are argyrodite (Ag 8 GeS 6), containing 5.7% germanium, and germanite (CuSFeSGeS 2), containing up to 10% Ge.), containing up to 10% Ge. Get price

Germanium

Some zinc-copper-lead ore bodies contain enough germanium that it can be extracted from the final ore concentrate. An unusual enrichment process causes a high content of germanium in some coal seams, which was discovered by Victor Moritz Goldschmidt during a broad survey for germanium deposits. Get price

Germanium

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbours silicon and tin.Pure germanium is a semiconductor with an appearance similar to elemental silicon. with an appearance similar to elemental silicon.

Minerals

A relatively low concentration of germanium in the initial solution (5.15 g/dm 3) also had an influence on hydrogen evolution during the process, especially at the beginning of the process. In the case wherein tin was present in the solution, it might act as an intermediate, i.e., tin was reduced with zinc dust, and later germanium was cemented with metallic tin. Get price

Zinc (Zn)

Zinc Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table.It is brittle and crystalline at ordinary temperatures, but it becomes ductile and malleable when heated between 110 C and 150 C. It is a fairly reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen. Get price

Review of germanium processing worldwide

2004/3/1It is planned to process the material at the Kokkola zinc refinery in Finland (Germanium, 2002). On September 9, 2003, Boliden and Outokumpu signed a Letter of Intent whereby Boliden intends to acquire all Outokumpu's mining and smelting operations within zinc and copper and to sell its Fabrication and Technology Sales units to Outokumpu.

Recycling

Zinc smelting is no exception: when refining zinc metal, by-products are produced with concentrated other metals. Silver, copper, sometimes even indium, and germanium are among these. While providing these concentrated by-products to other metal producers, zinc smelters and refineries get by-products from other metal producers. Get price

Zinc Anodizing

A military specification was issued for zinc anodizing, MIL-A-81801, Anodic Coatings for Zinc and Zinc Alloys, but it was cancelled in the mid-1990s.
