摘 要：<正>A numerical simulation analysis for reactions of chalcopyrite and pyrite particles coupled with momentum, heatand mass transfer between the particle and gas in a flash smelting furnace is presented. In the simulation, the equations gov-erning the gas flow are solved numerically by Eular method. The particle phase is introduced into the gas flow by the parti-cle-source-in-cell technique （PSIC）. Predictions including the fluid flow field, temperature field, concentration field of gasphase and the tracks of particles have been obtained by the numerical simulation. The visualized results show that the reac-tion of sulfide particles is almost completed in the upper zone of the shaft within 1.5 m far from the central jet distributor（CJD） type concentrate burner. The simulation results are in good agreement with data obtained from a series of experi-ments and tests in the plant and the error is less than 2%.
