本试验提出了一个从富锰渣冶炼烟尘中回收某些有价值元素的湿法冶炼工艺。首先烟尘直接用硫酸处理,然后通过控制适当的pH,锌锰被沉淀分离开来。最后,把它们转化为相应的硫酸盐和碳酸盐。在烟尘中的微量元素如镓、铟、铊等是通过萃取法分别提取的。试验表明,辛醇-(2)和N,N-二(1′-甲基庚基)乙酰胺是有效的萃取剂。 This experiment proposed a wet smelting process for recovering some valuable elements from manganese-rich slag smelting dust. First the soot is treated directly with sulfuric acid and then the zinc and manganese are separated by precipitation by controlling the appropriate pH. Finally, convert them to the corresponding sulfates and carbonates. In the dust of trace elements such as gallium, indium, thallium, etc. were extracted by extraction method. Experiments show that octanol - (2) and N, N-bis (1’-methylheptyl) acetamide are effective extractants.
