This research focused on the recovery of iron from ferrous grinding swarf. Grinding swarf comprised metal grindings, oil residue, and ceramic particles. Metalworking fluids provide better grinding properties by lubricating and cooling the interface between tool and material; however, it covers metal grindings after its use, and it is undesirable since the oil burns explosively during smelting operations for metal recovery. Based on the initial characterization, the sample contained about 78 % of metallic iron and 16 % of oil residue by weight (dry basis). Thus, aqueous washing with detergents was evaluated to obtain oil removed ferrous grinding swarf at different operating conditions. In addition to the aqueous washing, oxidation of ferrous grinding swarf at elevated temperatures was also conducted to find an alternative way to reuse the waste material as a pigment.
