Beneficiation is the process of sorting, cleaning and crushing glass. At the beneficiation plant, contaminants are removed from the feedstock: ferrous metals are removed by large magnets and nonferrous metals are removed via an eddy current. Contaminants such as plastic and paper are removed using negative or positive air pressure systems.
