摘要： PROBLEM TO BE SOLVED: To provide a method for producing zinc carbonate, which is applicable to any of facility systems such as a continuous tank system and a batch-treatment system, and enables an Fe content in a product obtained by ammonium carbonate dissolution-metal Zn ion exchange method to inexpensively, easy-operationally and certainly lower.SOLUTION: Process control of the method is carried out by periodically analyzing a Zn-containing solution after ion-exchange and filtration treatments by using an on-site usable Fe quick analysis method. Where, when the Fe content exceeds a control limit value, the process control is carried out so that the ion-exchange reaction and filtration are redone through again adding metal Zn to the Zn-containing solution in process before the crystallization process.

摘要： PROBLEM TO BE SOLVED: To specifically provide a simple, practical and effective method for separating wet dust in gas emissions from a blast furnace for iron manufacturing containing a large amount of carbon (C) into iron (Fe) and carbon (C) to reuse them in iron manufacturing.SOLUTION: A slurry mixture is made from wet dust and ultrasonication is carried out to the slurry. Then wet separation such as wet magnetic separation is applied to the slurry to separate it into a recovered material mainly containing iron and a recovered material mainly containing carbon. The recovered material mainly containing iron can be reused as an iron source for iron manufacturing after dezincification in a reduction furnace.
摘要翻译：要解决的问题：具体提供一种简单，实用和有效的方法，用于将含有大量碳（C）的铁制造炉的高炉中的湿粉尘分离成铁（Fe）和碳（C ）将其重新用于铁制造。
解决方案：浆液混合物由湿粉制成，并对浆料进行超声波处理。然后将湿分离如湿磁分离施加到浆料上以将其分离成主要含有铁的回收材料和主要含有碳的回收材料。主要含铁的回收材料可以在还原炉中脱锌后作为制铁生产的铁源再利用。版权所有（C）2012，JPO＆INPIT
