Abstract: An apparatus, method, and system are provided for separating material. In some embodiments the separator may include a deck. The deck may accept the material to be separated at a feed end and may provide separated output material at a discharge end. The flow of the material along the deck from the feed end to the discharge end may define a feed direction. The deck may be subject to a vibration or conveyance aligned with the feed direction. The deck may include riffles or corrugations. The riffles may be oriented at an angle relative to a direction of the vibration or conveyance, or at an angle relative to the feed direction. The deck may be subjected to an end-to-end elevation or slope. The end-to-end slope may be positive/downhill, negative/uphill, or zero.

Abstract: The invention relates to a method for the processing of metal scrap, in particular steel scrap, wherein the metal scrap material is treated with at least one fluid with a view to removing surface coatings before a spectroscopic analysis of the metal scrap composition is performed. On the basis of this composition the metal scrap can then be sorted and further processed in a purposeful manner. Moreover, the fluid used for the removal of the surface coatings can be suitably treated to recover the metal constituents contained therein. On the one hand, a resource-conserving and economic recovery of metals, in particular zinc, contained in surface coatings is achieved by means of the inventive method and, what is more, the method also enables a purposeful sorting of metal scrap material to be performed for a variety of uses in the iron and steel producing industry.
