The emerging new energy industry has significantly increased the demand for iron phosphate and nickel-cobalt precursors in lithium-ion batteries. Using crude ferronickel derived from smelting of laterite ores to produce these enables efficient valorization Fe, Ni, Co. However, limited leaching efficiency necessitates strategies enhance its acid properties. This study proposes a synergistic approach using roasting atmosphere temperature activate water-quenched ferronickel. With increasing temperature, face-centered cubic (FCC) Ni-Fe phase transformed into body-centered (BCC) phase. When exceeded 800 °C, however, newly formed BCC reverted FCC N2 atmosphere. Carbon could be removed by CO2 atmosphere, thereby preventing reversion. After at °C 1 h under efficiencies Co, Fe were 92.88, 91.88, 89.20%, respectively, with unleached portion consisting cementite an unconverted Following 1000 corresponding 99.65, 99.37, 96.75%, achieving near-complete due elimination.
