| titleOfInvention | A kind of method of comprehensive utilization of arsenic sulfide slag |
| abstract | A kind of method of comprehensive utilization of arsenic sulfide slag, including 1）Pulp, 2）Filter-press dehydration, 3）Drying, 4）Roasting, is 1. pumped into the arsenic sulfide slag after drying powder burner and is burnt with gas injection, makes arsenones disperse to be thoroughly mixed with combustion air in the firing chamber of powder burner to form stabilization burning by the atomizing of powder burner；2. when the arsenic sulfide slag sulfur content of burning is relatively low, the assisted gas burner configured by firing chamber completes the heat supply to firing chamber；5）Gas solid separation, 6）Arsenic is received in cooling.The present invention realizes that sulphur, arsenic are separated with valuable metal, and the various elements in vulcanization arsenic filter cake are reclaimed, and is produced without new dangerous waste residue.Product sulfuric acid, arsenic trioxide and valuable metal mixing slag are formed, arsenic trioxide average purity can reach more than 99%, and the arsenic rate of recovery reaches more than 97%. |
