【摘要】 铝土矿在磨矿过程中存在明显的选择性磨矿行为 ,Al2 O3 在粗粒级富集 ,而SiO2 在细粒级富集。在磨矿过程中加入助磨剂后 ,这一过程可得到强化 ,与未加助磨剂相比A/S大于 9的产品产率可进一步提高 9% ,Al2 O3 回收率提高 10 %以上。更多还原

【Abstract】 There is evident selective grinding behaviour in the grinding of bauxie ore, Al 2O 3 concentrating in coarse fraction while SiO 2 in fine fraction. Addition of grind aid can intensify this process. Compared with the grinding without grinding aid, the grinding with the addition of aid can increase the weight percent of the product with A/S ratio greater than 9 by 9% and the Al 2O 3 recovery by over 10%.更多还原
