测量了高岭石、伊利石、叶蜡石和一水硬铝石在阳离子捕收剂反浮选时的润湿性和动电行为。通过分析矿物的晶体结构,对测量结果进行了解释。根据矿物的晶格参数计算了矿物的零电点,计算的零电点值与试验测得的等电点值有很好的吻合。等电点测量值和零电点计算值的减小顺序为:一水硬铝石>高岭石>伊利石>叶蜡石,这与Al-O断裂键数目以及Al-O断裂键数目与Si-O断裂键数目的比值减小顺序基本一致。阳离子捕收剂在矿物表面上的吸附作用主要为静电作用。反浮选分离含铝硅酸盐矿物和一水硬铝石获得了满意的结果。
The wettability and electrokinetic behavior of kaolinite, illite, pyrophyllite and diaspore in the reverse flotation of cation collector were measured. By analyzing the crystal structure of minerals, the measurement results are explained. According to the lattice parameter of mineral, the zero point of the mineral is calculated. The calculated zero point value is in good agreement with the measured isoelectric point value. The decreasing order of the isoelectric point and the calculated value of zero point is: diaspore> kaolinite> illite> pyrophyllite, which is related to the number of Al-O fracture bonds and the number of Al-O fracture bonds and The ratio of the number of Si-O fracture bonds decreases in the same order. Cationic collector adsorption on the mineral surface is mainly electrostatic. Anti-flotation separation of alumino-silicate minerals and diaspore obtained satisfactory results.
