摘　　要：以六偏磷酸钠为参照,研究了铝土矿的正浮选工艺条件,进行了新型抑制剂ZMD的对比试验,研究表明ZMD的浮选效果更优。以ZMD为抑制剂,针对两种铝土矿原矿,进行了正浮选闭路试验,取得了优异的工艺指标:针对原矿铝硅比为5左右的铝土矿,获得了铝硅比7.08、氧化铝回收率90.22%的精矿;针对原矿铝硅比为3左右的铝土矿,获得了铝硅比7.72、氧化铝回收率70.56%的精矿。With common depressorcalgon as a reference, the authors studied on the direct flotation process of bauxite, carried on the contrast tests for the new depressor ZMD. Results indicated the flotation performance of ZMD was better. Employing ZMD as the depressor, circuit tests for two dif- ferent bauxite ores were conducted, and the outstanding index was gained. Processing the bauxite ores of A/S = 5 and A/S = 3, the A/S of final concentrate are 7.08 and 7.72 ; the recovery rate of AI2O3 are 90.22% and 70.56% ,resoectivelv.
