Abstract:
Agglomeration methods were successfully applied to the beneficiation of germanium in a germanium-bearing carbonaceous shaly sandstone deposit. Grades of up to 0.1 per cent germanium could be obtained in the pH range of 8 to 10, representing about a 25-fold improvement. Recoveries were virtually complete, with tailings reduced to 2-9 ppm. The inexpensive low-grade oil in the agglomerate could serve as a source of fuel for flash ignition to liberate the germanium in the concentrate as a volatile compound. Author
