Process for the recovery of gallium and germanium from

Process For The Recovery Of Gallium And Germanium From

A method is disclosed for recovering gallium andor germanium from fly ash which comprises pelletizing the fly ash, treating the pellets in the presence of an oxidizing gas at a temperature of from about 900 C. to just below the fusion temperature of the pellets, treating the pellets in the presence of a reducing gas at the same temperature range, and recovering gallium andor germanium suboxides

On The Geological Availability Of Germanium Springerlink

Dec 29, 2013 Based on a detailed statistical analysis of chemical data published in the scientific literature, estimates were made of the minimum amounts of recoverable Ge contained within sulphidic zinc ores and coals, given current processing technologies. It is expected that at least 119 kt 7 kt in zinc ores and 112 kt in coal of recoverable germanium exist within proven reserves at present ...

Gallium nitride GaN principally was used to manufacture optoelectronic devices. ICs accounted for 72 of domestic gallium consumption, optoelectronic devices accounted for 25, and research and development accounted for 3. About 80 of the gallium consumed in the United States was contained in GaAs, GaN, and gallium phosphide GaP wafers.
