A novel collector RL for flotation of bauxite

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%.
