摘　　要：从选矿拜耳法选矿流程特点入手,结合实验室试验数据,分析低品位铝土矿选矿工艺对后续拜耳法系统的物耗及运行效果的影响。综合考虑选矿和拜耳法两大系统特点,提出选矿工艺综合评价指标及下一步的研究方向,期望引发进一步提高选矿拜耳法生产氧化铝工艺水平的思考。Starting from the characteristics of the dressing process of Bayer process, and combining with the evidence of laboratory test data, discusses the influence of the processing technology of low grade bauxite on the material consumption and operation effect of the subsequent Bayer process. Taking into account the characteristics of the two systems of dressing and Bayer process, a comprehensive evaluation index of mineral processing technology and the next research direction are put forward,and it is expected to lead to further improve the level of ore dressing bayer process of alumina production process of thinking.
