“…However, the prohibitive costs of the reagents and instrumentation is a compelling aspect to look for a new approach. Moreover, maximum techniques are not utterly utilized on a large scale [7,[29][30][31][32][33][34][35][36].…”

The recovery and repurposing of valuable substances from iron-bearing wastes is challenging and vital from economic and environmental perspectives. Herein, maghemite (γ-Fe 2 O 3) particles were synthesized from different iron-containing waste materials by simple chemical precipitation method using HCl, NaOH, and Na 2 CO 3 , followed by calcination. Subsequently, the optimum pH value for the precipitation of iron from solution, and calcination temperature for getting γ-Fe 2 O 3 were found at 12 and 350°C, respectively. The final products were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), particle size analysis (PSA), thermogravimetry/differential thermal analysis (TG/DTA), and vibrating sample magnetometry (VSM). The formation of γ-Fe 2 O 3 was anticipated from XRD and FT-IR studies, while TG/DTA data supported their excellent thermal permanence. SEM studies showed that the γ-Fe 2 O 3 particles were relatively irregular, mostly spherical structured with a particle size ranged around 0.2-0.35 μm. PSA confirmed the high specific surface area of γ-Fe 2 O 3 particles, and the largest one was found from the iron dust. VSM measurement assured the existence of ferromagnetic properties in γ-Fe 2 O 3 particles at room temperature. The findings reveal that this procedure is a viable way to prepare γ-Fe 2 O 3 particles from iron-containing waste materials.
