摘　　要：采用拜耳法对某地区铝土矿进行了溶出性能研究，探讨了原矿配料分子比、循环母液浓度和石灰添加量对矿石溶出性能的影响，研究结果显示，适当提高配料分子比、石灰添加量及循环母液浓度，溶出率会增大。控制配料分子比在1．4～1．5之间、石灰添加量在8．5％～16％时，最佳的相对溶出率可以达到95．19％。Bayer Process was adopted for the digestion performance study of bauxite, the effect of raw materials dosing molecular proportion, circulating mother liquor concentration and lime additive amount on bauxite digestion performance were discussed in this paper, The research findings show, properly increasing dosing molecular proportion, lime additive amount and the circulating mother liquor concentration, the dissolution rate will be increased. The best relative dissolution rate will be 95. 19% by control the dosing molecular proportion in 1.4 - 1.5, and the lime additive amount in 8.5% - 16%.
