The ferrous grinding swarf was obtained from the automobile industry in North America. Fig. 1(a) shows the image of the as-received ferrous grinding swarf. The relatively wide size distribution of the sample can be observed in the photo. It was agglomerated together to form a large size due to its moisture and oil residue.
