单矿物浮选试验结果表明 ,在阳离子捕收剂DTAL作用下 ,调整剂SFL在pH =2～ 12范围内活化高岭石的浮选 ,而在弱酸性条件下对一水硬铝石的浮选影响较小。弱酸性条件下的人工混合矿分离试验表明 ,随着原矿中一水硬铝石的含量的增加 ,精矿铝硅比显著上升 ,氧化铝的回收率也随着提高 ;在调整剂SFL的作用下 ,精矿铝硅比进一步提高。动电位测试研究表明 ,与SFL作用后的一水硬铝石和高岭石的负电位显著增加 ,使得阳离子捕收剂通过静电作用力更容易吸附在矿物表面上吸附。吸附量的测试表明 :SFL增加了在高岭石表面的捕收剂吸附量 ,而在一水硬铝石表面的捕收剂吸附量有所减少。
Single mineral flotation test results show that under the action of the cationic collector DTAL, the regulator SFL activates the flotation of kaolinite in the range of pH = 2 ~ 12, while the floatation of diaspore in weakly acidic conditions Selected less affected. The results of artificial mixed ore separation under weak acid condition show that with the increase of diaspore in ore, the ratio of aluminum to silicon in concentrate increases significantly and the recovery of alumina increases with the increase of SFL Under the aluminum and silicon concentrate further improve. The study of the potentiodynamic test shows that the negative potentials of diaspore and kaolinite after the interaction with SFL increase significantly, making the cationic collector more easily adsorb on the mineral surface by electrostatic force. The adsorption capacity tests showed that SFL increased the amount of collector adsorbed on the surface of kaolinite and decreased the amount of collector adsorbed on the surface of diaspore.
