| Abstract: |
| The indium-rich zinc acid-leaching residue with 0.046% of indium and 50% of iron was reductively volatilized in a rotary furnace. The results indicate that the evaporation rate of indium can reach 67.56% under the conditions including particle size of In-Fe slag of -3 mm, proportion of granular coal of 30%, feed speed of 200 kg/h, kiln rotational speed of 3 r/min, volatilization temperature of 1 250 ℃, and air coefficient of 1.1. |
