Melting and Casting of Copper and Aluminum Alloys: Part

Because the density difference between the copper melt and the particles is very high the particles tend to float to the surface (e.g. the density of copper at 1100°C is 7.96 g/cm 3 while iron oxide has a density of 5.25 g/cm 3). However Stokes law predicts that even at high density differences very small particles tend to stay suspended.
