Outline
Experiments were performed to study the effect of quaternary ammonium salt Y28, as a collector, on the flotation performance of diaspore and gangue silicate minerals of kaolinite and muscovite, and the interaction mechanism between Y28 and the surface of minerals was also explored by analyzing adsorption capacity, contact angle, zeta potential, FTIR analysis and XPS analysis. The results show that with the collector Y28 at a dosage of 90 mg/L and pulp pH of 7, the recoveries of diaspore, kaolinite and muscovite were 25.63%, 83.21% and 81.24%, respectively. The collector Y28 is primarily adsorbed onto the surface of the minerals by physical adsorption, with the adsorption strength in the following descending order: kaolinite>muscovite>diaspore.
