| Abstract: |
| Rhenium-bearing slag was treated by oxidizing roasting, alkali roasting, and acid leaching. Volatilization rate of rhenium is 98% above when roasted at 600 ℃ for 6 h with oxygen concentration of 40%. Water leaching rate of tungsten is 99.5% above after roasted at 600 ℃ for 5 h with mass ratio of alkali and slag of 3. Leaching rate of nickel and cobalt is 99.4% and 99.2% respectively when water leaching slag is acidic leached under the conditions including temperature of 90 ℃, sulfuric acid concentration of 2 mol/L,L/S of 3, and leaching time of 3 h. Tantalum is enriched in acid leaching slag. |
