Description: Valuable metals such as Ni, Cu and Co are partially lost in the flash furnace slag during the smelting process. These metals are present in the slag either as dissolved metals or as physically entrained matte particles. In this study, the matte particle size distribution in the slag was measured and a mathematical model was developed to simulate the settling process of matte particles in the slag. The influence of the iron content in the slag on the loss of valuable metals was analyzed and a linear relationship between the Co and Fe content in the slag was found.In the process of matte separation from the slag, the matte particles inevitably collide and coalesce due to their velocity differences. A numerical model was developed to model the changes of the matte content and particle size distribution in the slag considering particle collision and coalescence.
