赤泥综合利用评述

摘要

Red mud or bauxite residue was a waste produced from the alumina industry. There were many production methods of alumina in our country, such as Bayer process, sintering process and mixed combination process, and the types of red mud were various and their characteristics had great difference, which added more difficulty on comprehensive utilization of red mud. The present situation of comprehensive utilization of red mud was summarized, and the idea to produce the glass - ceramics by mixing a certain proportion of red mud from sintering process and mixed combination process with quartz tailings and amounts of quartz was put forward.%赤泥是氧化铝生产过程中排出的固体粉状废弃物。我国生产氧化铝方法比较多,如拜尔法、烧结法和混联法等,导致赤泥的种类多和性质差别较大,增加了赤泥的综合利用的难度。总结了目前赤泥综合利用的现状,并提出用烧结法和联合法赤泥按一定配比混合工业废料石英砂尾泥及适量石英生产微晶玻璃的想法。
