However, there has been limited research focusing on the production of nano Fe from iron ore tailings (IOT). In recent report, Liu et al. successfully synthesized zero-valent Fe from IOTs by employing coke as the reducing agent [101, 102]. This transformation occurred at a temperature of 900 °C in the absence of oxygen.
