Abstract
A device for obtaining a material from a mixed fraction (including particles of a desired material and particles of another material with different optical properties) has a first sorting apparatus and at least two further sorting apparatuses below the first sorting apparatus. From the first sorting apparatus, a major fraction is introduced into a first further sorting apparatus and purified further there, while a minor fraction is passed into a second further sorting apparatus and processed further there.
