Abstract:
1. A method for processing a waste stream comprising the steps of: receiving the waste stream comprising non-ferrous metal components; processing the received waste stream with a first air separator to generate a first heavy fraction waste stream; processing the first heavy fraction waste stream in a first destoner to generate a second heavy fraction and a light fraction; crushing the second heavy fraction in a crusher; screening the crushed second heavy fraction to separate the components of the crushed second heavy fraction into a first size and a second size, wherein the first size is larger than the second size; processing the first size of components of the second heavy fraction in a second destoner to generate a third heavy fraction; and processing the second size of components of the second heavy fraction in a small materials separator to further concentrate the non ferrous metal component in the second size.
