PPM Pure Metals

Nichteisenmetalle wie Germanium, Gallium, Indium oder Tellur kommen eher selten vor und fallen meist als Nebenprodukte bei der Gewinnung von Zink, Blei, Kupfer und Aluminium an. Dies bedingt eine begrenzte Produktionskapazitt, die den hohen Preis fr diese Nichteisenmetalle verursacht. Get price

Recovering in, Ge and Ga from zinc residues

A novel solvent extraction process has been developed to selectively recover indium, germanium and gallium from the cement residue sulfuric acid leach solutions in a hydrometallurgical zinc plant. The key work was to determine a special organic molecule for gallium and germanium extraction. Continuous countercurrent tests on the mini-pilot plant level were performed successfully with 90.7%, 94 Get price

The Extraction of Gallium from Zinc Ores

Abstract. The discovery of small amounts of gallium in zinc ores showed the possibility of its presence in a small quantity of zinc ore residues on hand at the Institute. Germanium had been previously extracted from the ore, and later, part of the zinc was recovered. During this work, the presence of gallium was shown by spectroscopic tests, and indium was at the same time shown to be absent. Get price
