摘　　要：我国南方数家钢铁厂瓦斯灰(泥)中含有具有利用价值ZnO。本法以瓦斯灰(泥)为原料,不需前期加工,用NH4Cl作萃取剂提取Zn制取活性ZnO。本法条件温和,较传统的酸法消耗少,腐蚀小,萃取剂可回用,所以成本低廉,加之国家有关优惠政策,使用本法利用瓦斯灰(泥)有较大的优势。It is found that there is a valuable ZnO in wet dust of blast furnace of several iron and steelworks in the south China. Active ZnO could be produced by using NH 4Cl as extract agent under mild condition. The technique has many advantges as compared with acid method.It is good in less corrosivcness,less expending,need not process in advance,reuse of extract agent and preferential policy of government.There is a higher potential in the use of the blast furnace wet dust by this method.
