| titleOfInvention | A kind of arsenic alkali slag reduction smelting treatment method |
| abstract | The invention discloses a method for reducing and smelting arsenic-alkali slag. The method mixes arsenic-alkali slag with a carbonaceous reducing agent, and then reduces and smelts to obtain arsenic vapor, crude antimony and reduced slag, and the arsenic vapor is condensed to obtain metal arsenic products; the reduced slag The main component is Na 2 CO 3 , which can be directly used as a de-arsenic agent to return to the antimony refining and de-arsenic process, or Na 2 CO 3 crystals can be obtained through a water leaching-concentration-crystallization process. The method obtains metal arsenic and crude antimony through one-step reduction, and at the same time regenerates Na 2 CO 3 , which simplifies the process compared with the existing process, reduces the production cost, realizes the reduction, harmlessness and resource utilization of arsenic, and solves the problem of The environmental protection problem has produced considerable economic benefits and is suitable for industrial promotion. |
