Production of reduced iron powder using ultra-fine iron concentrate

Abstract

The using of the iron to extract reduced iron with T_Fe≥69.5% Al₂O₃+SiO₂<0.3% was studied. Preparation of reduced iron powder in this experimental research can produce ultra-pure magnetite concentrate. The quality of the final product reaches the product standard of SC 100.26 and NC 100.24.
