Abstract
A method for separating mixtures of solid materials includes incorporating a ferromagnetic particulate material into a mixture of solid materials and, after the incorporating step, separating the mixture of solid materials into at least two groups based on the magnetic and frictional properties of the different components of the mixture of solid materials. The ferromagnetic particulate material can differentially incorporate into or adhere to different components of the mixture of solid materials. The different components of the mixture have different frictional properties and, after the incorporating step, the different components have different magnetic properties.
