Review of germanium processing worldwide ScienceDirect

2004. 3. 1. Production processes to recover germanium consist of two main stages comprised of the generation of germanium concentrate followed by actual production of germanium end products. Hydrometallurgical processes are favoured and these are based on the precipitation of germanium as either a hydroxide or sulphide or alternately with tannic acid.

High Purity Germanium, a Review on Principle Theories and

2017. 9. 30. main sources: zinc ores processing and coal fly-ashes. While most of Germanium produced is a by-product of zinc processing, some Germanium is extracted from the fly ash at coal-burning power plants [3]. The contribution of coal as a source in the overall supply of Germanium worldwide can be estimated in the range be-tween 20% and 30% [4].

Germanium: Current and Novel Recovery Processes

2018. 1. 22. Germanium (Ge) is considered a critical element due to its many industrial applications; Ge is a metalloid used in solar cells, fiber optics, metallurgy, chemotherapy, and polymerization catalysis. The main sources of Ge are sulfides ores of Zn, Pb, and Cu, coal deposits, as well as by-products and residues from the processing of these ores and coals (e.g., smelting flue dust and coal fly ashes).

Germanium Wikipedia

2021. 1. 20. Germanium is created by stellar nucleosynthesis, mostly by the s-process in asymptotic giant branch stars. The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars. Germanium has been detected in some of the most distant stars and in the atmosphere of Jupiter.

Geraniums: How to Plant, Grow, and Care for Pelargoniums

2021. 3. 31. Keep the plants in shade for a week, then place them in a sunny spot (they need all the sun they can get) and keep them cool. During winter, geraniums grow best with night temperatures of 50° to 60°F (10° to 16°C) but will survive if they drop to
