| titleOfInvention | Gradient arsenic removing method for high-arsenic metallurgical wastes |
| abstract | The invention provides a gradient arsenic removing method for high-arsenic metallurgical wastes, which is generally suitable for comprehensive arsenic removing treatments of high-arsenic smoke dust generated in the smelting process of lead, zinc, antimony, copper, tin and the like, high-arsenic anode mud generated in the electrolytic process of wet lead, silver, copper and the like and other metallurgical wastes. The method comprises two stages of water leaching arsenic removal and oxidizing acid leaching arsenic removal and specifically comprises the following steps of: first, selectively dissolving out free arsenic trioxide and water soluble arsenate (like sodium arsenate and potassium arsenate) through water leaching; and then further leaching out indissolvable arsenate and arsenic sulfide in the water leaching residue as well as little incomplete arsenic trioxide dissolved out by water by using a mixed leaching liquor of acid and water soluble oxidizing agent. The method provided by the invention has the advantages of low consumption of acid and alkali, high arsenic removing efficiency, safety, environment friendliness and suitability for arsenic removing treatment of various arsenic contained metallurgical wastes, in particular for arsenic removing treatment of the smoke dust with high content of free arsenic trioxide. |
