摘　　要：铝土矿中的硫是影响氧化铝生产中的重要杂质之一,硫的含量直接影响到氧化铝生产的指标。高硫铝土矿的矿石性质和赋存状态研究表明,硫主要是以黄铁矿的形式赋存在矿物中,硫在氧化铝生产过程中的危害及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、焙烧预处理脱硫以及添加还原剂烧结法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,并指出目前工业生产中选用浮选工艺除硫是很好的选择。研究低污染、低成本而又高效的除硫工艺,已成为选矿工作者的重点之一。Sulfur which is one of the important impurities in bauxite affects alumina production index. Study on ore properties and occurrence status indicated that the sulfur in alumina ores mainly occurs as pyrite. In recent years several desulfurization process had been studied and developed, including flotation, roasting pretreatment reducing sintering and so on. The performance and results of these process were reviewed and flotation was considered a best choice. Developing efficient desulfurization processes with low pollution and low cost bad become one of the key tasks for mineral processing workers.
