摘　　要：赤泥是氧化铝工业生产过程中产生的废弃物,由于其高碱性特点,无害化大宗利用成为难题。根据赤泥原料的特点,开展了铝厂赤泥生产烧结砖的初步试验研究。在小试的基础上进行了半工业试验,得出了用赤泥制作烧结砖的工艺技术参数,并就存在的问题提出了几点建议及进一步研究的必要性,完善赤泥制砖的整套技术,加快赤泥资源化利用的步伐。According to the characteristics of the raw material of red mud, a preliminary experimental study on the production of fired bricks from red mud in an aluminum plant is carried out. On the basis of the small test, semi-industrial tests are carried out, and the technical parameters of making fired bricks with red mud are obtained, and some suggestions on the existing problems and the necessity of further research are put forward to improve the whole set of red mud brick making technology.

关 键 词：铝厂赤泥 制砖工艺 试验研究
