高硫铝土矿脱硫浅析

Analysis on Desulfurization of High-Sulfur Bauxite

我国铝土矿资源瓶颈制约的加剧,威胁我国铝工业的生存和发展。而我国大量的高硫铝土矿还没有获得工业应用,提高高硫铝土矿资源利用率显得非常迫切。本文对近年来研究的几种脱硫工艺,其中有浮选法脱硫、生产氧化铝湿法脱硫、焙烧预处理脱硫等几种脱硫技术,对不同脱硫工艺的效果分别进行了评述。

The bottleneck of China＇s bauxite resources intensifies threatened the survival and development of China＇s aluminum industry. In China, a large number of high sulfur bauxite was not got industrial use. Therefore, accelerating the development and applied research of high sulfur bauxite and bauxite resource utilization was very urgent. In recent years, several desulfurization processes were studied, including flotation, roasting pretreatment reducing sintering and so on. The effects of these different processes on desulfurization were analyzed.
