Germanium Gallium Ore Leaching with Sulfuric Acid
2018 9 23 Therefore, to extract germanium and gallium from the ore, it is necessary to solubilize the iron compounds. Musto Explorations LTD, former owner of the mine, employed a 3 stage counter current process using sulfuric acid and SO2 to leach approximately 80% of the germanium and 90% of the gallium from the ore Olsen, 1989 .
Determination by Neutron Activation of Gallium and
Summary A procedure is given for the simultaneous determination by neutron activation of gallium and germanium in iron meteorites or other similar materials. Germanium is separated from interfering activities by solvent extraction from 8 Ν HCl into carbon tetrachloride followed by distillation as GeCl4. The chemical yield is determined colorimetrically using phenylfluorone.
