摘　　要：通过对铝土矿反浮选新型捕收剂TR和传统捕收剂1231重要浮选性能的对比研究,揭示了TR在不加任何其他调整剂的情况下,即能在广泛的pH范围内实现高岭石和一水硬铝石的反浮选分离,且TR的使用量比1231低约50%;TR在用常规调整剂的情况下,精矿铝硅比为10.13,回收率77.14%,明显优于使用1231作捕收剂时的指标,而且精矿泡沫量很小,消泡容易。The comparative study on flotation performance between the new collector TR and the traditional collector of 1231 for reverse flotation of bauxite was made to reveal that TR can realize the reverse flotation separation of kaolinite and diaspore in a wide range of pH value without any adjustment agent added. Moreover, TR consumption can also be lowed by about 50% than 1231. With the conventional adjustment agents, TR made the Al-Si ratio of concentrate at 10.13 and recovery of 77.14% , which are much better than by 1231 as the collector. As well, the concentrate has less foam and is easily defoaming.
