5 Why is resource mining important Metals are a limited resource Global market: constantly growing demand for metals Less metal content in mined iron ore and more difficulties to open up new mines Not enough mining in Europe to keep up with the demand, dependency on resources from unstable regions outside of Europe Even more important: Developing existing resources that are already in circulation Conservation of natural resources No mining and contamination of valuable landscapes and habitats Metal mining from existing resources that are already in circulation! 17th November rd International Recycled Aluminium Conference DHZ AG, Stefan Eberhard, Switzerland 5

7 Bottom ash less Volume Development municipal solid waste in Switzerland Constantly growing amount of municipal solid waste Incinerator obligation in Switzerland since 2000, in Germany since 2005 Direct landfilling is a waste of valuable raw materials Trend of flammable waste in Switzerland: 80% 20% Source: BAFU und VBSA More waste = more bottom ash = larger potential for metal recovery 17th November rd International Recycled Aluminium Conference DHZ AG, Stefan Eberhard, Switzerland 7

16 supersort fine Fraction < 3 mm This fraction contains roughly 3-4% NF-metals «Acceleration machine» Light & fine particles Heavy & chunky particles Non-ferrous-metal separator Concentrate with 50-65% NEcontent (depending on input) Concentration Classification Raw material Refining Depending on the input, additional recovery of 1% non-ferrous metals with supersort fine. 17th November rd International Recycled Aluminium Conference DHZ AG, Stefan Eberhard, Switzerland 16

17 supersort fine : Results Separation and concentration of metals works very well More value through the recovery of metal-particles below 3 mm Time consuming analytics for accessing the quality Existing and recyclable deposits of gold und silver Higher contents of heavy metals (especially copper, gold and silver) in the < 3 mm fraction compared to the other productfractions Raw material from supersort fine : Products can t be sold directly needs supersort metal for refining 17th November rd International Recycled Aluminium Conference DHZ AG, Stefan Eberhard, Switzerland 17
