| 摘 要： | 研究了一水硬铝石、高岭石及叶腊石等单矿物在RL为捕收剂时的浮选特性，考察了各种调整剂、难免离子对浮选体系的影响，在此基础上进行了人工混合矿和实际矿石的分离试验。实际矿石闭路试验结果表明：采用RL为捕收剂，碳酸钠和六偏磷酸钠为调整剂，精矿中Al2O3和SiO2的品位分别为70．74％和6．37％（精矿铝硅比为11．11），Al2O3的回收率达到90．52％。

| Abstract: | The flotation properties of single minerals such as diaspore, kaolinite and pyrophyllite in bauxites have been investigated using RL as collector. Effects of regulators and unavoidable ion on flotation have also been studied. Based on the results of single minerals tests, the separation experiments of artificial mixed minerals and bauxite ore have been carried out. The concentrate with the grade of Al 2O 3 70.74% and SiO 2 6.37%, and the recovery of Al 2O 3 90.52% is obtained by means of closed circuit experiment of ore when using RL as collector, Na 2CO 3 and (NaPO 3) 6 as modifiers. |
