The Designation of the Collector in Aluminosilicate Minerals Flotation and the Study of Its Mechanism

摘要

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-l,3-diaminopropane from the perspectives of solid-philic group and nonpolar group by applying the kaolinite crystal model in Curis software. It also studies the function mechanism of this newly developed reagent in flotation by applying flotation solution chemical calculation, ζ-potential test and infrared spectrometry test.
