Calcium carbonate, renowned for its affordability and potent dephosphorization capabilities, finds widespread use as a agent in the direct reduction roasting of high-phosphorus oolitic hematite (HPOIO). However, precise impact on iron recovery minerals with phosphorus within HPOIO, particularly mineral transformation rule mechanism, remains inadequately understood. This study delves into nuanced effects calcium carbonate through magnetic separation. A (DRI) boasting 95.57% content, 93.94% recovery, 0.08% an impressive 92.08% is achieved. underscores how addition facilitates generation apatite from catalyzes formation gehlenite by reacting silicon dioxide alumina, inhibiting reduction. Furthermore, it increases liquid phase, enhancing dissociation metallic monomers during grinding procedure, thus facilitating efficient dephosphorization.
