摘　　要：在实验室分批浮选试验的基础上建立了浮选回收率模型,通过回归分析获得了某磷铁矿石浮选动力学参数。应用JKSimFloat软件建立了一个闭路循环浮选回路,将获得的参数输入到软件中,并对其它设备参数进行了合理的优化设置后,模拟计算了该浮选回路的选别效果。与实验室闭路浮选试验结果相比,模拟的精矿品位基本相当,而模拟的精矿回收率偏低。A flotation recovery model was built up on the basis of batch flotation test, and the flotation dynamic parameters of a kakoxene ore were obtained by regression analysis. Using JKSimFloat software, a locked-cycle flota-tion circuit was designed, and the metallurgical results of the flotation circuit was simulated by inputting those dynam-ic parameters and other equipment parameters after being optimized to the software. Compared with the experiment re-sults ,the simulated concentrate grade is approximately equal, while simulated concentrate recovery is slightly lower.
