  • A novel collector RL for flotation of bauxite | SpringerLink

    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

  • The Designation of the Collector in Aluminosilicate ...

    The main gangue minerals in bauxite ore are kaolinite, illite and pyrophyllite. The bauxite reverse flotation aims to float them out. In this essay, a certain type of bauxite is taken into account to design and synthesize the N-Alkyl-1,3-diaminopropane from the perspectives of solid-philic group and nonpolar group by applying the kaolinite crystal model in Curis2 software.
