本发明含铁、锰、锌、铅等元素烟尘的回收方法,属于处理非矿石的材料,生产有色金属及其化合物的技术领域。利用碱浸烟尘,将其中的锌、铅等浸出到碱溶液中,固体和液体分离后,向浸出液中加入硫化钠,在室温下搅拌生成硫化锌和硫化铅混合物,经水洗再放入稀盐酸液(pH<5)中,生成氯化锌溶液, The method for recovering soot containing iron, manganese, zinc, lead and the like belongs to the technical field of processing non-ore materials and producing non-ferrous metals and compounds thereof. Using alkali leaching dust, the zinc, lead and the like are leached into the alkali solution, and after the solid and the liquid are separated, sodium sulfide is added to the leaching solution and stirred to form a mixture of zinc sulfide and lead sulfide at room temperature, washed with water and then added into dilute hydrochloric acid Liquid (pH <5), generate zinc chloride solution,
