    Steel mill dust recycling is a comparable young business which only started to become more interesting in the late eighties. Even though strong R&D activities have been found since then, the Waelz kiln process is still the dominating technology. However, there are some potential alternatives and also interesting innovations within the Waelz kiln process.

  2. Mass Flow Analysis and Metal Losses by the Degradation Process of Organic-Containing WEEE Scraps

    Fabian Diaz, Sebastian Florez and Bernd Friedrich

    Article first published online: 7 OCT 2015 | DOI: 10.1002/cite.201500064

    Recycling of WEEE scraps is becoming more and more important. This article compiles information and experimental results about pyrolysis as an intermediate process that overcomes huge challenges in WEEE recycling like improved recovery of valuable metals, better control of hazardous substances, improved process control and increased recycling capacity.

  3. Thermomechanical Treatment of Metal Composite Fractions

    Martin Rotheut, Thomas Horst and Peter Quicker

    Article first published online: 5 OCT 2015 | DOI: 10.1002/cite.201500062

    Within the scope of the investigation, a combined pyrolysis-mechanical treatment of metal composites was examined. Alongside light shredder fractions, electric waste and metal concentrates from landfill were treated. The aim was the separation of the composites to enable extensive metal recovery in the form of high grade concentrates.

  4. Gemeinsames Recycling von Flachbildschirmen und Bleigläsern

    Robert Wolf and Michael Stelter

    Article first published online: 5 OCT 2015 | DOI: 10.1002/cite.201500060

    Für bleihaltige Gläser aus alten Bildschirmröhrengeräten sowie für Flachbildschirme gibt es derzeit kein wirtschaftliches Recyclingverfahren. Flachbildschirme enthalten Indium und Zinn in geringen Konzentrationen, deren Rückgewinnung von strategischer Bedeutung ist. Es wird ein Verfahren vorgestellt, das beide Bildschirmabfälle zusammen recycelt.

  5. Schwermetallentfernung aus Gewässersediment durch Bioleaching im Praxismaßstab

    Kati Görsch, Petra Hoffmann, Uwe Schlenker, Andreas Aurich and Andreas Zehnsdorf

    Article first published online: 5 OCT 2015 | DOI: 10.1002/cite.201500079

    Die Entfernung von Sedimenten aus Gewässern erfordert häufig deren anschließende Behandlung zur Reduzierung von Schadstoffgehalten (z. B. Schwermetalle). Die Potenziale eines Verfahrens aus kombinierter Konditionierung und mikrobieller Laugung werden für die Behandlung von Sedimenten im großtechnischen Praxismaßstab dargestellt.
