摘要： A method for recovering ruthenium from a spent ruthenium-based catalyst carried on aluminum oxide includes: drying, calcining, and cooling a spent catalyst; grinding the spent catalyst into black powder; placing the black powder in a fluidized bed reactor, purging the reactor with hydrogen and heating the black powder to obtain ruthenium metal, then heating the black powder in a mixed atmosphere of oxygen and ozone to obtain RuO4 gas; absorbing the RuO4 gas with a sufficient amount of hydrochloric acid to obtain a H3RuCl6 solution; adding an excess oxidant to the H3RuCl6 solution to oxidize the H3RuCl6 into H2RuCl6; adding excess NH4Cl to the H2RuCl6 and then filtering, and washing the filter cake to obtain solid (NH4)2RuCl6; and reducing the solid (NH4)2RuCl6 by hydrogen to obtain ruthenium metal.

摘要： The copper sulfide ore is leached in the halide bath without using a special oxidant but with the use of only air. The copper and gold in the copper sulfide ore can be leached at high leaching ratio.The treating steps are as follows. (1) Copper leaching process (CL). The raw material is charged into the first acidic aqueous solution, which contains cupric chloride, ferric chloride, 7 g/L of hydrochloric acid, and sodium chloride. The post-leach liquor contains copper in cuprous state ions and copper in cupric state ions. (2) Solid-Liquid separation step. The resultant solid and liquid of CL step are separated. (3) Air oxidation step (OX). Air is blown into the post solid-liquid separation liquor. The copper in cuprous state ions are oxidized to the copper in cupric state ions. The iron leached in the step (1) is oxidized. Simultaneously, the impurities leached in the step (2) are precipitated. (4) Copper extracting step (CEX). The copper is recovered from the post-liquor of the step (3) (5) Gold recovering step (AL). The residue separated in the step (2) is added to the leach liquor similar to that of the step (1). The steps (1) and (5) are carried out under the atmospheric pressure and at the temperature of boiling point or lower, while blowing air into the leach liquor.
