摘　　要：中低品位一水硬铝石型铝土矿浮选后的精矿中除含有原矿的腐殖酸类等有机物外还有一定量的有机浮选药剂,在后续的拜耳法生产氧化铝流程中,这些有机物对氧化铝的生产和产品质量有负面影响。介绍了浮选精矿中有机物的来源及对拜耳工艺的影响,提出了降低有机物影响的几点措施。There are some native humic acids and floating agents in the flotation concentrates of low grade bauxite. These organic matters could influence Bayer process and alumina products quality. The organic matters sources and effects on Bayer process are introduced. The measures for reducing prganic matters influence on Bayer process are pointed out.
