One technique is magnetic density separation, which has recently been developed by Umincorp. Magnetic density separation uses a ferrofluid that generates a vertical mass density gradient when in the presence of a magnetic field. In other words, as you move from the top of the fluid to the bottom, the apparent mass density of the fluid increases.
