摘　　要：研究了铝土矿中的有机物黄腐酸对赤泥沉降性能影响,考察了黄腐酸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黄腐酸负面作用的条件.It was studied that the effects of the humic acid on properties of the mud sedimentation in bauxite. The effects of different concentration of humic acid on settlement rate, overflow clarity and download L/S were studied. And elimination of the negative effect of flocculate on the humic acid was also studied.
