摘要:
赤泥是氧化铝生产过程中的强碱性固体粉末状废弃物，本文简要概述了赤泥的基本特性，着重阐述了国内外从赤泥中回收有价金属元素铁、铝、钛和其他稀土元素的工艺，并对其进行了评析。最后对赤泥的综合利用进行了展望，而赤泥与红土镍矿制备铁镍合金的方法前景广阔。
Abstract:
Red mud is a strong basicity solid waste residue of the digestion of bauxite ores with caustic soda for alumina production. This paper gives a overview of the basic characteristics of red mud and also puts great emphasis on the recycling technologies both at home and abroad, which mainly deal with those valuable metals come from red mud, such as Fe, Al, Ti and RE elements. And last, this paper points out there is a high trend towards the comprehensive utilization of red mud, hence, it is a booming prospective concerning the productive process of preparing iron nickel alloy by the smelting of red mud and lateritic nickel ore.
