实验室研究表明,从有色冶金铅锌粉尘中以低毒硫化物形式分离出砷是可能的。去除砷的方法是:在310—350℃的条件下,粉尘与元素硫预先接触1h,使所有组分都转为硫化物
Laboratory studies have shown that it is possible to separate arsenic from low-toxic sulphides from non-ferrous metallurgy lead-zinc dusts. The method of arsenic removal is that the dust is pre-contacted with elemental sulfur for 1 h at 310-350 ° C, turning all the components into sulfide
