Reverse Flotation of Bastnaesite Using a New Type of Saturated Fatty Acid Modified Collector DT-2
摘要
Abstract
A new type of saturated fatty acid modified collector DT-2 was synthesized in laborato-ry, the flotation characteristics of bastnasite, calcite, barite and fluorite were investigated.Test re-sults showed that the recovery of bastnasite was 26%, and the recovery of gangue minerals was over 95%when the pulp temperature was 20 ℃, the amount of collector was 33.34 mg/L and the pH was 8.Hence, DT-2 can be used as anti-flotation collector to realize separation of cerium ore and gangue minerals.The results of infrared spectrum and zeta potential detection showed that the adsorption state of DT-2 on the bastnasite or gangue minerals was not electrostatic adsorption but chemical adsorption The results provide a theoretical basis for the application of DT-2 in the sepa-ration and purification of bastnasite.关键词
