| 中文摘要: |
| 研究了火法熔炼从废催化剂中回收银的工艺。通过添加造渣剂CaO形成CaO-Al2O3二元渣系，当CaO加入量为7 kg，熔炼温度1500℃，时间6 h，银的回收率大于99%；银比重大，沉在坩埚底部，渣相和金属相分离，得到纯度大于99.8%的银。 |

| The process of recovering silver technology from waste silver catalyst by fire smelting was studied. CaO-Al2O3 binary slag system was formed by adding the slagging elements of calcium oxide, when the amount of calcium oxide is 7 kg, melting temperature of 1500℃, time is 6 h, the recovery rate of silver more than 98%; the specific gravity of silver is bigger, sink the bottom of crucible, slag phase and the metal phase separation, obtain high purity of silver more than 99.98%. |
