本发明涉及一种高碱高锌高炉瓦斯灰的回收方法及应用。高碱高锌高炉瓦斯灰的回收方法包括如下步骤：采用水进行高炉瓦斯灰的脱碱处理,重结晶进行钾钠元素的分离,通过碳热还原对高炉瓦斯灰的脱锌处理,采用浸出剂分离氧化锌粉,通过球磨、磁选富集脱锌灰得到铁精矿粉以及铁尾矿。本发明将回收的铁尾矿用于制备发泡陶瓷中。本发明高碱高锌高炉瓦斯灰的回收方法针对高炉瓦斯灰中的碱金属、锌铅等低沸点金属进行有针对性的处理,同时作为二次资源进行回收。

The invention relates to a method and application for recovering gas ash from a high-alkali and high-zinc blast furnace. The recovery method of high-alkali and high-zinc blast furnace gas ash includes the following steps: using water to deal with blast furnace gas ash, recrystallization for separation of potassium and sodium, carbothermal reduction to dezincification of blast furnace gas ash, using leaching agent The zinc oxide powder is separated, and the dezincification ash is enriched by ball milling and magnetic separation to obtain iron concentrate powder and iron tailings. The invention uses the recovered iron tailings to prepare foamed ceramics. The method for recovering high-alkali and high-zinc blast furnace gas ash of the present invention performs targeted treatment on the low-boiling point metals such as alkali metals, zinc and lead in the blast furnace gas ash, and at the same time recovers it as a secondary resource.
