鞣酸体系下黄铜矿与黄铁矿浮选动力学分析
Flotation kinetics of chalcopyrite and pyrite in tannic acid system
摘要
Abstract
In the practice of Cu-S sulfide flotation,a lot of reagents were added to achieve the separation of copper sulfide and iron sulfide minerals. In fact,The separation of Cu-S sulfides can be realized by using the difference of the flotation rate of sulfide minerals in the flotation reagent system. Flotation kinetics ofchalcopyrite and pyrite in tannic acid has been investigated by flotation test. The flotation rate constants were calculated for chalcopyrite and pyrite in tannic acid system. Results showed that tannic can depress the pyrite and pyrite while has weekly impact on the flotation of chalcopyrite. In the tannic acid system,the flotation rate of chalcopyrite is obviously higher than that of pyrite. The average flotation rate constant is 0.8 while pyrite flotation rate constant of is only 0.31. The flotation kinetics model of chalcopyrite and pyrite were fitted by mathematical software. Results showed that chalcopyrite and pyrite flotation kinetics model apply to the improved differential level model(D21).关键词
