This study investigated for leaching and adsorption characteristics of rare metals from domestic steelmaking dust in which they exist at very low concentration in the a mixture of high concentration of iron, zinc, and silicon. The major constituents in this steelmaking dust are iron, zinc, silicon and alkali metals. The dust were contented of rare metals such as boron, gallium and vanadium. Of the boron contained in the dust, 72% leached with 3.0 mol/dm3 sodium hydroxide solution where the pH of the final pregnant liquor is 13.8. To remove the impurity metals, they were precipitated as their hydroxides by adjusting the solution pH being 10. The selective concentration of boron was done using a chelating resin column with a functional group of glucamine type, and the eluate containing 5.6 g/dm³ of boron was obtained. By employing 2.5 mol/dm³ sulfuric acid for leaching vanadium and gallium from the solid residue resulting from leaching with alkalic solution, the leach liquor containing 0.038 g/dm³ of gallium and 0.028 g/dm³ of vanadium was obtained. Gallium and vanadium in the leaching solution were concentrated by use of a chelating resin column with a functional group of aminocarboxylic acid type after reduction of ferric ion to ferrous ion and pH adjustment. The elute was conditioned and passed again through the column. Gallium was concentrated to 13g/dm³ and vanadium to 9.7g/dm³ in the resulting elute.
