摘　　要：研究了铝土矿中的有机物草酸钠对赤泥沉降性能的影响,考查了草酸钠不同浓度条件下对赤泥沉降速度、溢流浮游物含量和底流压缩液固比的影响,同时研究了加入絮凝剂消除草酸钠负面作用的条件.The effect of sodium oxalate on the sedimentation properties of mud in bauxite was studied. The effects of concentration of sodium oxalate on sedimentation rate, overflow clarity and download L/S were investigated. And the elimination of the negative effect of sodium oxalate by adding flocculating agent was also studied.
