  • memproses zinc ore germanium equitreknederland.nl

    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 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.

  • How to Increase Germanium Extraction from Zinc

    Germanium is produced almost exclusively from waste residue of hydrometallurgical zinc processing operations (Llewellyn, 1989). Currently, highgrade 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).

    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
