摘　　要：以动力学参数K(浮选速率系数)为依据,来评判黄铜矿、黄铁矿快速浮选分离的可能性.首先,在不同矿浆浓度、浮选粒度及浮选机转速等条件下考察黄铜矿和黄铁矿纯矿物K值的变化,在一定程度上阐释了黄铜矿、黄铁矿快速浮选分离的动力学机理及其可能性;同时,为使黄铜矿、黄铁矿快速浮选分离技术在工业上具有适用性,进一步研究黄铜矿与黄铁矿组成的2种粒级的混合矿在适当浮选条件下的动力学特性.结果表明,控制适当的浮选条件,可扩大黄铜矿与黄铁矿之间的浮选速率差异,从而实现黄铜矿的快速优先浮选.To judge the possibility of rapid flotation separation on chalcopyrite and pyrite, the dynamics parameter K （flotation rate coefficient） was used as the basis. At first, through investigating the change of K value of chalcopyrite and pyrite pure minerals under the conditions of pulp density, flotation particle size and flotation machine speed, respectively, the dynamics mechanism and possibility of rapid flotation separation on chalcopyrite and pyrite was interpreted to some extent. Meanwhile, to make the technology of rapid flotation separation feasible on chalcopyrite and pyrite applicable in the industry, the dynamics characteristic of two mixed ore in different size fraction that composed by chalcopyrite and pyrite was further investigated. lt was proved that flotation rate difference between chalcopyrice and pyriec could be expanded through controling appropriate flotation conditions and then furfiued the rapid prioriey flotation of chalcopyrite.
