<p>It was found that the gallium in phosphorus furnace treater dusts can be concentrated by contacting the treater dust with a slurry of an alkaline earth compound, such as calcium hydroxide, and separating the solubilized gallium from solution. The gallium can be further concentrated by contacting the gallium-containing solution with carbon dioxide to provide a gallium-containing precipitate. Alternatively, the gallium can be concentrated using other methods.</p> |
