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 circuitteston the ore show that, using RLas collector, Na₂CO₃and (NaPO₃)6as modifiers, the grade of Al₂O₃and SiO₂are respectively 70.74% and 6.37% in concentrate (Al/Si 11.11), and the recovery of Al₂O₃can reach 90.52%.

Key words: collector; modifier; unavoidable ion; flotation properties; bauxite
