Abstract:
FLSmidth is under taking developing a process to direct treatment of magnetite ore. After magnetic ore separation, two pyrometallurgical options are evaluated to reduce Iron and decrease the phosphorous content in the final product. Magnetic separation, iron water vapor reduction with enriched hydrogen is tested. A thermodynamic and experimental investigation to develop a new process to extract Iron from their ores is then carried out.Iron sample with 40-48% Fe and levels of 0.3-0.9% of P are tested to obtain a metallic iron product of > 90% and less than 0.05% of P. The kinetics of the reaction are determined by measuring the weight change of a sample with time in water vapor at temperatures between 1000-1350oC.
