摘要
根据国内外含铝矿物预脱硅研究结果,简述了化学法预脱硅、生物法预脱硅和物理法预脱硅的优缺点,并提出了借鉴铝土矿预脱硅法,对粉煤灰先进行改性处理然后预脱硅的建议,使粉煤灰得到有效综合利用。
The research progress on pre-desilicification from ores containing aluminum and silicon was introduced.Advantages and disadvantages of chemistrical method,biography method and physics method for pre-desilicification were described.It was suggested that fly ash should be desiliconized after modification treatment by means of the method of removal silicon from bauxite.This contributed to utilization of comprehensive resources.
