Abstract
A method and apparatus for magnetically beneficiating a raw sample, such as coal or lunar soil is disclosed. The beneficiation is achieved using a novel of fractionating the sample into components of different magnetic susceptibilities. The results of the fractionation may be used to determine the type of magnet to be employed for large scale operations, as well as the appropriate fraction or fractions to be recovered for further processing.
