Processing Zinc Ore Germanium

Processing Zinc Ore Germanium

Germanium Statistics and Information - USGS

2021-11-25  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

traditional roast-leach-electrowinning process of zinc hydrometallurgy, Ga and Ge can only be retrieved from these zinc sulfide concentrates with low rates of recovery and significantly high costs. Development of oxygen pressure leaching provides a more efficient way to extract germanium and gallium from a zinc sulfide concentrate.
