我厂在1982年曾对生铁高炉烟尘中锌的贮存状态等作过详细调查,得出高炉挥发出的锌主要富集在瓦斯泥中,锌含量为10—40％,并利用0.36m~3的反射炉进行了回收实验,但收得率较低。文献指出,氧化锌在国内外市场上的需求量大量增加,硫酸锌的需求量也将增加,因此从污泥中直接回收氧化锌或硫酸锌产品是十分必要的。 Our factory made a detailed investigation on the state of zinc storage in pig iron blast furnace dust in 1982, and concluded that the zinc volatilized from the blast furnace is mainly concentrated in the gas mud with a zinc content of 10-40%, and 0.36m ~ 3 Of the reverberatory furnace recovery experiments, but the yield is lower. The literature pointed out that the demand of zinc oxide in the domestic and foreign markets increased greatly, the demand of zinc sulfate will also increase, so the direct recovery of zinc oxide or zinc sulfate products from sludge is very necessary.
