| 摘 要： | The flotation properties of single minerals such as diaspore, kaolinite and pyrophllite in bauxites were investigated using RL as collector. The effects of regulators and unavoidable ions on flotation were studied. Based on the results of single minerals flotation, the separation experiments of mixed minerals and bauxite ore were carried out. The results of closed circuit test on the ore show that, using RL as collector, Na2CO3 and (NaPO3)6 as modifiers, the grade of Al2O3 and SiO2 are respectively 70.74% and 6.37% in concentrate(Al/Si 11.11 ), and the recovery of Al2O3 can reach 90.52 %.

| Abstract: | The flotation properties of single minerals such as diaspore, kaolinite and pyrophllite in bauxites were investigated using
RL as collector. The effects of regulators and unavoidable ions on flotation were studied. Based on the results of single
minerals flotation, the separation experiments of mixed minerals and bauxite ore were carried out. The results of closed circuit
test on the ore show that, using RL as collector, Na2CO3 and (NaPO3)6 as modifiers, the grade of Al2O3 and SiO2 are respectively 70.74% and 6.37% in concentrate (Al/Si 11.11), and the recovery of Al2O3 can reach 90.52%.
