Improving plastic waste separation with magnetic fields

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. When plastic particles are added to this ferrofluid, the various particles move to a height ...
