Separation of metal-containing fractions from slag or production streams for waste incineration slag, by processing slag into fractions, separating iron-containing fractions and separating non-ferrous metal-containing fractions

摘要

Separation of metal-containing fractions from slag or production streams comprises supplying and processing the slag into fractions, pre-separating fractions to separate iron-containing fractions, and separating non-ferrous metal-containing fractions using an eddy current separator (26-28). The fractions have a size of not > 5 mm and are kept dry when non-ferrous metal-containing fractions are separated. An independent claim is included for a separation device used for separation of metal-containing fractions from slag or production streams.
