On the geological availability of germanium SpringerLink

2013-12-29  Germanium has been known to occur as an impurity in sphalerite for over a century (Urbain 1909), and techniques for its extraction from zinc smelting residues were developed early on, long before it had found any technological applications (Buchanan 1916, 1917; Dennis and Papish 1921).From the 1930s onwards, due to the advent of new and very sensitive spectrographic analytical methods
