摘要
在对炼铁烟尘灰的物料特性研究的基础上,采用高温挥发,使物料中Zn、Pb、B i、In、Te等主要有益组分含量富集3倍左右,同时降低物料中可溶硅等有害组分,为物料中有益组分的湿法提取提供了良好的条件。
Based on the study of the material characteristics of the dust, the high temperature vaporization process was used to make the valuable components, such as Zn, Pb, Bi, In and Te, enrich in the smoke ash about three times. At the same time, the harmful components such as soluble Si etc. can be decreased. This contributes to good conditions for the wet extracting of the valuable components from the material.
