USGS Minerals Information: Germanium
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.copper mineral byproduct - perkinspreschool,Mar 04, 2018 · Byproduct of metal price meltdown is a higher silver price MINING . Aug 5, 2015 70% of silver is mined as a byproduct gold, base metal mine closures as a by-product in mines which target copper, gold, zinc, and lead.Byproduct metal requirements for U.S. wind and solar,,Tin oxide (SnO 2), zinc oxide (ZnO), and aluminum-doped zinc oxide (AZO) are, however, viable substitutes to ITO in these applications , , , . Given that these readily available alternatives do not require byproduct metals, the potential material requirements of the TCO layer in thin film solar PV is excluded in this analysis.
