摘要 神华集团自主研发的粉煤灰盐酸法协同提取技术,将粉煤灰中铝及有价元素镓、锂、钪等协同提取,最终将酸浸液中的有用成分全部回收利用。酸浸后剩余的固体残渣主要由非晶态的二氧化硅和氧化铝组成,活性较高,可以作为硅基产品原料来制备分子筛、保温板、瓷质砖、橡塑填料、白炭黑等。酸溶渣综合利用研究技术不仅解决了酸溶渣堆存带来的环境问题,而且又可获得较高利润,是循环经济产业链上重要的组成部分。

Abstract: Shenhua Group has independently developed synergistic extraction technology of fly ash and hydrochloric acid, the aluminum in the fly ash and the valuable elements gallium, lithium and cesium are synergistically extracted. Finally, the useful components in the acid leaching solution are all recycled. The solid residue after acid leaching (acid-soluble residue) is mainly composed of amorphous silica and alumina, as well as with high activity. It can be used as a raw material for silicon-based products to prepare molecular sieves, thermal insulation boards, porcelain bricks, rubber and plastic fillers, white carbon black, etc. Acid soluble-residue comprehensive utilization research technology can not only solves the environmental problems by white-mud accumulation, but also obtains higher profits, which is an important part of the circular economy industrial chain.
Key words:  fly ash    hydrochloric acid    acid-soluble residue    silicon-based products    comprehensive utilization
