Abstract Scope |
In the flash furnace for copper smelting, copper loss in the slag is an economically important topic. It is known that the matte droplets size, one of the major factors of mechanically entrained copper loss, is complicatedly determined by the local number density, initial size and chemical composition of concentrate. Numerical simulation based on dynamic model can clarify the various factors’ effects instead of experimental approach restricted in industrial high temperature field. In this study, collision and coalescence behavior of the large number of droplets consisted of matte and slag with various size assumed in the flash smelting reaction shaft is specifically calculated by smoothed particle hydrodynamics method considering interfacial deformation. This numerical simulation visualizes interfacial deformation of droplet, coalescence of matte and interference of slag, and it showed that the interfacial energy has a great effect on the size growth of the matte. |
