The company was founded in Qujing, Yunnan, China in 2000. It was listed on the Shanghai Stock Exchange in 2004. Germanium Solutions | Umicore,Germanium's abundance in the Earth's crust is approximately 1.5 ppm. Only a few minerals contain appreciable amounts of germanium, and none in mineable deposits. Most germanium is recovered as a by-product of zinc smelting and from the fly ash of coal-burning.

Concentrations of Zn (910 ± 840 ppm) and Ge (65 ± 58 ppm) are tens to hundreds of times greater than in Martian meteorites and estimates for average silicate Mars.Germanium and Indium Recovery from Zinc Metallurgy by,,Zinc was almost fully leached in sulphuric acid, forming soluble zinc sulphate. In the case of germanium and indium, a maximum leaching yield of 85% was achieved. One of the reasons of the incomplete leaching might have been the adsorption of Ge and In containing species on the surface of SnO 2 particles formed during leaching.Yunnan Chihong Zinc & Germanium Co Ltd (600497) Stock,,Get the latest Yunnan Chihong Zinc & Germanium Co Ltd (600497) real-time quote, historical performance, charts, and other financial information to help you make more informed trading and,Refractive-index measurements of zinc germanium,,A method to determine the absolute refractive index of materials available in the shape of flat wafers with parallel sides by using interferometric techniques is presented.
