Gallium Solvent Extraction
Solvent extraction with the organophosphate, OPAP, proved very successful for recovering over 98 pct of the gallium from solutions with pH values as low as 0. Gallium extraction using OPAP was hindered when ferric iron was present in solution. Therefore, it was necessary to maintain the iron in the filtrate in a reduced state.
Germanium Gallium Ore Leaching with Sulfuric Acid
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).
