Recovery of Iron Powder Through Process Optimization and Characterization of Mild Steel Scrap Using Electrolysis Process
https://orcid.org/http://orcid.org/0000-0003-2505-6505
Iron powder was extensively used in pharmaceutical, food fortification, compressed sinter and preparation of ferrous salts. It was basically produced through atomization, chemical reduction, thermal reduction, pulverization and electrolytic deposition. In the on-going research a noble approach has been made to recover iron powder directly from mild steel scrap using mono-polar and multi-polar electrolytic cell arragements in an optimized process parameter of 15 A current, voltage 7–10 V, pH 3–5, current density 0.5 A/cm2, time 3 h and electrolytic concentration of the bath 30–50 g/l and 55 A current, voltage 3–5, pH 3–6, current density 0.45 A/cm2, time 4 h and electrolytic concentration of the bath 60 g/l, respectively. It yields 88.7% and 93.10% iron powder reciprocally. The recovered product was characterized through Sieve analysis, optical microscopy, SEM–EDX, atomic absorption spectrophotometer and X-ray diffraction to know the behaviour of grain and its purity. Results reveal that 99.6–99.8% particles have iron values and show the habits of α-iron, dendritic in shape and BCC structure. Observations also delinate that grains were much finer as compared to other processes.
