The effects of dephosphorization agents (SiO2, Na2CO3 and Al2O3) reduction time on phosphorus gasification during pre-reduction sintering were studied. results indicate that the rate apatite by carbothermal is 23%, adding SiO2 Al2O3 25%, optimal 36% Na2CO3. increased from 13% to 31% with 20 min 60 min. Thermodynamic analysis shows promotion effect stronger than Al2O3, thermodynamic conditions a...

Developing the innovative technology for efficient utilization of high-phosphate iron ore was inevitable choice resource strategy. In this paper, exploring a new method gasification removal phosphorus by sintering based on biomass. Combined with theoretical analysis and experimental research, effects different conditions (biochar type, addition proportion, basicity) reduction behavior were stud...
