| Abstract: |
| Based on theories of minimum free energy and modified quasi-chemical solution, Rand-MQC coupling algorithm was applied to establish mathematical model of multiphase balance for thermodynamic analysis of high-intensity copper flash smelting, and a typical high-strength production case was calculated. The effects of oxygen consumption for one ton ore (VOPTR) and flux rate (RFLUX) on activity and content of equilibrium products were investigated. Calculation and thermodynamic analysis results show that calculation errors of copper matte and slag phase composition are both less than 2%, which are close to production measurement value. VOPTR and RFLUX are recommended to be controlled at 215 m3/t and 11%, in order to obtain high copper matte grade and better control of copper content and Fe/SiO2 ratio in slag. |
