Abstract
Gallium extraction from waste material generated by high-temperature furnaces is being investigated as part of the Bureau of Mines recycling research program. The flue dust from the production of elemental phosphorus contains gallium at levels greater than in materials being processed for gallium by the aluminum and zinc industries. Gallium is present at levels of 300 to 900 ppm in phosphorus flue dust. If it were economically feasible to quantitatively extract the gallium available in this flue dust, it would meet current U.S. consumption. A combination soda fusion-water leach process is being developed to extract gallium from phosphorus flue dust and other waste materials. The procedure has extracted 80 pct of the gallium in optimization tests. Details of the laboratory-scale development are discussed together with the analytical procedure required to accurately determine gallium at the parts per million level.
